WARRANTY DISCLAIMER Due to the intended usage of the products in this catalog, they are sold WITHOUT WARRANTY OR ANY IMPLIED WARRANTY OF MERCHANTABILITY OR FITNESS FOR THE INTENDED PURPOSE. Installation of parts intended for "off-highway" use could adversely affect the vehicle manufacturer's warranty coverage.

All weights specified are approximate and subject to manufacturing tolerances.

PERFORMANCE & STREET SERIES VALVES

Designed for the enthusiast preparing a stock or mildly modified street engine, or a bracket racer seeking maximum value for his dollar, the Performance or Street Series valves are the perfect choice. These dependable valves are also offered in Street Flo versions providing significant flow gains without head porting. All valves in both these series feature chrome stems, hard tips, swirl polished underhead areas, and fully machined combustion faces.
In addition to the vastly superior strength and fatigue characteristics of Manley NK-844, our exclusive intake material exhibits an uncanny ability to resist chordal fractures.

In an excellent sealing combustion chamber, the intake valve is actually deformed by the fuel explosion and pushed up into the port. The effect of this continuous

Further proof of the superiority of the Manley Severe Duty® valves is evident in our comprehensive fatigue tests. In normal operation where valve float is non-existent, a valve will experience 20,000 to 25,000 lbs of applied stress. However, when valves bounce on the seat the stress immediately soars to 40,000 to 60,000 lbs. Manley exhaust valves (at 40,000 psi and 1400°F) ran to 100,000,000 (one hundred million) cycles while competitors' offerings failed at 100,000 cycles. That's 1000 times better fatigue life.

EXTREME DUTY VALVES

Top Fuel and Funny Car drag racers, Big Block Chevy marine enthusiasts, and Small Block Chevy restricted carburetor circle track competitors will all benefit by the use of XtremeAlloy exhaust valves. Exotic steel is required simply because of the enormous heat imposed on the exhaust valves in these applications. quickly becoming a missing pie-shaped piece. Manley NK-844 is the absolute best choice of material to combat disastrous chordal fractures.

SEVERE DUTY® VALVES

The "Pro Flo" Shape A MANLEY ORIGINAL

Bead Loc® valve keepers

The essence of the Bead Loc® groove is its simplicity and forgiveness. The groove itself is a straightforward .110” full radius. The contact points with a Bead Loc® radius lock are approximately 2:00 and 10:00 o’clock, not at the root of the groove. This system affords minimal vertical movement, especially when valve float is present, which means reduced erosion of the valve for enhanced service life.

Manley Performance supports both the “conventional” groove system and the Bead Loc® system with the most extensive line-up of the highest quality locks in the industry.
Both 7° & 10° valve locks.

Manley Valve Locks... simply the best!

Conventional vs. Bead Loc® Valve Stem Grooves

The groove in a valve stem, seemingly unimportant, in reality is vital to the success of a valve’s performance.
Imperfectly formed grooves, inferior or mismatched locks, and improper retainers can lead to catastrophic failure.

The so called “conventional” or square groove design has enjoyed enormous success.
But the success of a “conventional” groove is dependent upon precise machining.
First, the surface finish of the groove must be outstanding to guarantee against failure due to residual machining marks.

Next, the groove must have a precise .013” radius in the upper corner. Too small a radius leaves the groove subject to the dangers of a sharp fillet.
Too large a radius leaves open the possibility of the groove being abraded in this area by the upper inside edge of the tang of the lock.
Also, an oversized radius leaves a reduced horizontal shelf in the groove which is, or should be, the only contact point with the tang of the lock.
Contact by the lock in the root of the groove is a disaster waiting to happen.

Perfectly formed “conventional” grooves with proper locks and retainers will deliver good service.
However, there are sub-standard components on the market that can conspire to destroy a correctly machined groove.

The essence of the Bead Loc® groove is its simplicity and forgiveness.
The groove itself is a straightforward .110” full radius.
The contact points with a Bead Loc® radius lock are approximately 2:00 and 10:00 o’clock,
not at the root of the groove.
This system affords minimal vertical movement, especially when valve float is present,
which means reduced erosion of the valve for enhanced service life.

Manley Performance supports both the “conventional” groove system and the
Bead Loc® system with the most extensive line-up of the highest quality locks in the industry.

LocCap SYSTEM
Manley Performance LocCap System
• The ULTIMATE valve lock/wear cap assembly
• Designed specifically for Fuel, Alcohol and Pro Mod Racers

First developed by our engineering team in the late 1990s for NASCAR applications, Manley’s LocCap system is designed to retain the wear cap on the tip
of the valve by employing an external bead on the wear cap that —when the system is assembled— resides within an internal “retention channel”
located on the I.D. of the valve locks. Manley’s valve train components group, headed by Manley GM Michael Tokarchik, refined the original designs
combining a state-of the-art steel alloy and ultra precise manufacturing techniques to achieve the goal of delivering a no compromises valve lock/wear cap assembly
for the supercharged classes.

Manley’s LocCap systems are available in true 7° as well as 10° and Super 7° assemblies for 3/8”, 11/32” and 5/16” stem valves in both Manley Bead Loc®
and conventional square groove configurations. In addition, Manley’s LocCap system retrofits to competitors’ “Lash Keeper” assemblies, maintaining original
valve spring installed height, valve overall length, valve tip length (0.250”) and retainer designs.

Both the LocCap valve locks and wear caps are precision machined using Manley’s TensileMax UHSS (ultra high strength steel).
The wear caps are thru-hardened to HRc 55 (harder than typical tool steel) to minimize wear due to aggressive rocker contact.
Manley’s proprietary heat treatment processes minimize distortion, thereby improving the fit of the wear cap and valve locks to the valve stem.
