Welcome to the LS Revolution

In recent years, LS engine technology has revolutionized
the GM performance aftermarket. Gen IV engines have set a new standard for factory horsepower and torque. To meet the growing demand of todays high performance engine builders and racing enthusiasts, engineers at RHS® designed an aluminum LS engine block for radical street and all-out racing applications.

Going beyond the limitations of other GM LS blocks,
the LS Race Block is available in both standard
(9.240") and tall (9.750") deck height combinations
and is engineered for maximum clearance around a
4.600" stroke crankshaft. This was done by raising the camshaft centerline (.388"/9.86mm) and including priority main oiling that shifts the oil galley outboard.
With this unique design, RHS® engineers also minimized windage in the rotating assembly – leading to superior engine lubrication at higher RPM.

To make it friendly for existing race applications, the block contains both factory and motor plate race mounts for Gen I, II, III and IV engines. And for quality assurance, RHS® conducts a CT scan (similar to a medical CAT scan) on each block to ensure maximum precision and consistency. Combine that with more standard features than any block on the market and the RHS® LS Race Block becomes the benchmark of LS power, strength and compatibility.

Standard Features:
• Engineered from extremely strong and durable, aircraft-
quality A357-T6 aluminum material
• Siamese cast bore walls (4.125" or 4.165" available)
with press-in cast iron sleeves
• Available in both standard (9.240") and tall (9.750")
deck heights with an extra-thick deck surface (.500"
standard deck/.750" tall deck); standard (5.87") and
tall (6.38") deck cylinder sleeves also available
• 6-Head bolt design (follows GM LSX strategy) with
full water jacket around cylinders; large valley windows
access inboard 6th head bolt
• Block design includes large front and rear -12AN
side feeds for serious dry sump setups
• Added material for oversized lifters (accepts 1.060"
bushing for keyed lifters) and lifter bosses that are
designed to clear tie bar lifters

CHOOSING CYLINDER HEADS The RHS® WAY
When Do Flow Numbers Matter?
While there are many ways to measure and compare heads – port volume, port flow, cross sectional area, air velocity, dimensions, chamber volume, valve size, etc. – the only thing that’s really important is that the entire engine performs as desired. So it's necessary to understand how some of these things work together and why flow numbers are not always the best comparison.

Most people understand the concept that if a cylinder head restricts the air/fuel flow, it will kill power. So the more air and fuel an intake port can flow, the better, right? It would be simple if you could put heads on a flow bench and declare the one that flows the most to be the best, but that’s just not always true.

It's easy to make a port flow more air – simply make it bigger. But doing that creates an engine that, more often than not, makes no torque and displays lazy throttle response. Plus, because there’s no standard for flow testing, unless you know exactly how the test was performed, raw flow numbers are not of great value and can easily throw you off track. The list of tricks a smart operator can use to create artificially high numbers on the flow bench is nearly endless. So when it comes to flow numbers, the only ones that are useful come from comparing two different heads on the same bench at the same time in exactly the same way.

The engineers at RHS® took a bold approach and designed their ports for the best performance on the engine and not necessarily on the flow bench. Taking into account the entire system when they design and port a head, they ensure every cylinder head works for the entire engine package to maximize power, efficiency and throttle response throughout the RPM range. Port flow numbers here aren't the goal, only a single indicator among many factors. How much the CFM intake flows isn’t the most important thing as long as the engine hits your horsepower and performance targets.

Another area where power can be improved but overall port flow can be hurt is in the throat, the area directly behind the seat. Controlling how the throat tapers as it approaches the valve seat can make the changes in seat angle less noticeable to the incoming air/fuel charge. By trying to target max power in lower RPM ranges, a smaller throat size is necessary. A throat size that’s 88 to 92% of the valve seat on a hot street motor helps the low-end torque. For all-out racing where the RPM is going to be much higher, the throat could be in the 92 to 98% range. A throat percentage this high will hurt flow bench numbers but will show up on the dyno in the upper RPM range.

The RPM range within which your engine will be operating also affects the ideal flow. Airflow velocity inside the ports is just as important as how much air the port can flow. It must be high enough to keep the air/fuel mixture in suspension, or fuel droplets will drop out of the airflow. Unburned fuel means lost power. Port velocity also creates better part throttle response and more power throughout the RPM range. The trick is to size the port appropriately in order to get the necessary velocity and then shape it to maximize flow.

It’s clear that choosing the correct head for your engine involves much more than just raw flow numbers. There are many important factors, and the smaller details are often more important than overall flow because they have a direct link to velocity and performance - and that's what really matters.

23° SMALL BLOCK CHEVY
CNC PORTED ALUMINUM CYLINDER HEADS

RHS® now offers a 23° aluminum head for Small Block Chevy applications that is CNC-ported from the factory for precision accuracy and durability. The CNC-ported 228cc intake and 82cc exhaust runners optimize volume, atomization and velocity, while the 69cc combustion hambers are CNC-ported to
elieve valve shrouding that occurs in "as cast" chambers when the edge of a valve is in close proximity to the combustion chamber wall. CNC-machining
the combustion chamber also improves the airflow efficiency of the cylinder heads. The 2.055" multi-angle intake and 1.600" radiused exhaust valve seats allow for superior airflow, thereby significantly increasing horsepower. In addition, these 23° SBC heads feature a refined water jacket for better water flow that reduces engine hot spots, while an extra-thick deck allows angle milling and improves head gasket retention in boosted and nitrous applications.
RHS® has designed a race-winning aluminum head that utilizes the latest in cutting-edge design technology to maximize airflow and boost horsepower in
both circle track and drag racing classes.

VALVE TRAIN

SPORTSMAN VALVES
COMP Cams® Sportsman Valves are available in a
variety of materials, diameters and stem lengths for
street and competition engines. The stainless steel
valves are made from 21-4N forged steel alloy with 50
HRc minimum hard tips (eliminates lash caps); these
valves deliver tremendous performance and durability.
The hard chrome-plated 11/32" stems utilize proprietary
oil retention surfacing. For extremely high revving
LS applications, RHS® engineers developed titanium
valves. Weighing 35 percent less than stainless steel,
titanium valves are a must for race applications where
valve float is not an option. For high temperature and
high boost applications, valves constructed from Inconel
superalloy are also available.

INTAKE MANIFOLDS

FAST™ LS XR™ & LSXRT™
INTAKE MANIFOLDS
FAST™ engineers teamed up with the airflow specialists at
RHS® to develop the LSXR™ Intake Manifolds for
rectangular port GM LS3 and LS7 engines and cathedral port LS1, -2, -6 engines, as well as the LSXRT™ for GM 4.8/5.3/6.0L cathedral port truck engines and cathedral port LS1, -2, -6 race applications where hood clearance is not a concern. Each intake manifold is constructed from an advanced polymer material that offers a host of benefits over aluminum aftermarket intakes, including lighter weight, increased strength
and improved heat dissipating characteristics. The LSXR™ and LSXRT™ series of manifolds also feature a 102mm air inlet that is perfectly suited to the FAST™ Big Mouth 102mm Throttle Body™, but the manifolds can also be used with OEM or aftermarket 90mm or 92mm throttle bodies.
Other features include an innovative multi-layer design with
removable runners for quick and easy disassembly and porting,
integrated nitrous bungs and a precise bolt-on fit that
permits the use of factory accessories and OEM fuel/emission
connections without adjustments or clearance issues.

FAST ™ BIG MOUTH THROTTLE BODIES™
When it comes to improving your engine’s performance, increased airflow is a key ingredient. The Big Mouth 92mm or 102mm Throttle Bodies™ for the LSXR™ and
LSXRT ™ Intake Manifolds increase airflow through a series of innovative design changes and a slightly enlarged throttle opening. Significant testing and engineering was conducted to optimize cross-sectional flow and eliminate airflow turbulence, especially at part-throttle operation.
The throttle blade’s thickness eliminates deflection, especially
in boosted applications. To improve throttle response,
the blade pivot is offset, while the beefed up linkage and dual
throttle spring mechanism ensure total throttle control.

• Better airflow than OEM or aftermarket 90mm units due
to enlarged opening and modified internal design
• Dual throttle spring mechanism and beefed up linkage
provide absolute throttle control
• Increased thickness of the throttle blade and the shaft
resists deflection, especially in boosted applications
• Offset blade pivot allows for smoother operations and
significantly improves throttle response

FREQUENTLY ASKED QUESTIONS***

I've picked out a set of heads,
any ideas on an intake manifold?
Look at velocity for low RPM torque and flow
for high RPM horsepower. Most carbureted performance intake manifolds are divided into two categories – dual plane and single plane. Dual plane manifolds are better for low and mid-range torque, and single plane manifolds (e.g., open plenum intake manifolds) emphasize mid and upper-RPM horsepower. In general, dual plane manifolds are better for street use; single plane manifolds are better for track use. Check with your intake manifold’s manufacturer for specific information. EFI manifolds differ in design characteristics, with improved mid-range and top end horsepower being common advantages of aftermarket EFI intakes.

Be sure and check for proper push rod geometry - length. Rocker arm should be in the middle of the valve at mid lift. Never starting out on the outside edge a no lift.

Based on my cylinder head choice, what
is the right pushrod size for my engine?
Some variables influencing pushrod length are engine block deck height, cylinder head dimensions, camshaft specifications, and many other characteristics that vary between individual engines.
We recommend you measure using a simple, inexpensive pushrod length-checking tool to verify geometry, and contact us so we can set you up with the correct pushrods the first time around.

What valve springs should I run with my cylinder head?
Valve springs should be chosen based on compatibility with the camshaft you plan to use. Figure 1 lists general guidelines to help you decide which spring to run based on pressure requirements for different types of cams. Your valve springs must also have coil bind clearance of at least .060" over the camshaft’s peak lift. All fully assembled cylinder heads offered by RHS® display maximum valve lift in their tech sheets. Beehive™ Springs typically have lighter open and seat pressures than conventional springs. The best way to choose a set of valve springs is to go with your cam manufacturer’s recommendation after first verifying that the valve springs will satisfy your cylinder head’s spring pocket diameter and installed height requirements.
Figure 1.
General Valve Spring Pressure Recommendations*

Camshaft Seat Pressure Open Pressure

Hydraulic & Solid Flat Tappet 100-130+ lbs . 270-350+ lbs .

Hydraulic Roller 105-135+ lbs . 280-350+ lbs .

Solid Roller (Street Pattern) 150-180+ lbs . 450-600+ lbs .

Solid Roller (Race Pattern) 190-300+ lbs . 600-1000+ lbs .

*General guideline only – consult with your camshaft manufacturer for exact valve spring recommendations.

What kind of camshaft should I run with my new cylinder heads?
Figure 2 lists a “ballpark” range of camshaft durations to consider based on the intake runner volume of various RHS® cylinder heads. Unless you run a high valve lift (above .550") camshaft with 220 $184.52 or 235cc heads, you may not realize any performance advantage over cylinder heads with
smaller intake runners. We do not make recommendations based on advertised duration because of the various rating methods used by cam manufacturers, which makes for poor camshaft comparison. Remember – this is a general guideline. Your intended application or the advice of your engine builder should always take precedent when it comes to cam
selection on an individual basis.

FREQUENTLY ASKED QUESTIONS

Any idea on what type of aftermarket
headers I can run with RHS® cylinder heads?
In most cases, aftermarket headers are more than acceptable – they are encouraged. They will typically improve the performance potential of any cylinder head (or engine, for that matter). However, RHS® cylinder heads feature spark plug locations that are optimized for better atomization to ensure maximum performance. Therefore, it is important to check for fitment issues prior to ordering aftermarket headers – especially in unique, less common engine applications. In some applications a "shorty" style plug can be used for additional clearance; these plugs allow additional clearance between the spark plug boot and headers.

Can you tell me if I have enough piston-to-valve
clearance based on my engine data? And where
do rocker arm ratios figure into all of this?
Piston-to-valve clearance varies between individual engines.
Not checking it could lead to your camshaft having more lift
than clearance, which can bend your valves, or worse, punch holes in your pistons – necessitating engine tear down or even a ground-up engine replacement. Write down your clearance once you’ve measured it, so if you decide to swap cams, some easy math can tell you if you have enough clearance. Measurement needs to be taken again if engine modification occurs, such as swapping blocks or cylinder heads, machining deck surfaces or changing head gaskets. Refer to your existing measurement to verify fit if you swap to a higher lift camshaft or change to a higher rocker arm ratio.

The following equations help explain the effect rocker arm
ratio has on valve lift. As an example, we look at a common
rocker swap: Small Block Chevy – switching from the factory 1.5-1.52 ratio to a 1.6 ratio. Assuming a .500" lift camshaft (based on 1.5 ratio), we first need to calculate lobe lift. The equation is as follows:
Valve Lift/Rocker Ratio = Lobe Lift
Lobe Lift x New Rocker Ratio = Valve Lift
Plugging in the numbers gives us: .500"/1.5 = .333" lobe lift.
Rearranging the equation gives us our gross valve lift with the new rocker ratio: Inserting the cam and rocker specs gives us .333 x 1.6 = .533" – a substantial difference in lift. Many people say, “Switching to a 1.6 from a 1.5 gives .030" more lift!” This is true in some cases, but this number is a ratio – not a constant. Do not assume lift increase will be any set number. Do the math, record the numbers and verify that you have clearance. You'll never have to worry about putting a valve through your brand new forged racing pistons!

* If running a split pattern cam with different intake and exhaust lobe lifts, do the equation twice (once for each lobe) to accurately calculate your gross valve lift.

BASIC ENGINE FORMULAS
The following equations explain the basic engine
measurements needed for more effective cylinder
head selection and compatibility. Here, is used as
a mathematical constant that represents the ratio of
the bore's circumference to its diameter.
