Replacement Series Valves

These valves are made from stainless and steel materials that are suitable for all stock rebuilds and unleaded conversions. Low prices and top quality make these valves a great deal for standard use. Available for foreign, domestic and motorcycle applications.

Seat Saver Valves

is proud to introduce our newest series of valves. Seat Savers will save you time and money by allowing you to save work on seats by offering economically priced replacement valves in .030" oversized heads. All other specs on the valves are stock. This allows you to still use the valve guides of your choice.

Economical Portflow Series Stainless Valves/
Quicksilver Series Stainless Valves

These valves are stainless, one piece, chrome stem, hard tip, 21-4N EV8, ideal for both competition and street applications. They are similar in material and design to competition valves, but manufactured in large production runs for all of the most popular applications. Because of the fully automated (robotic) production, SEV-series valves are priced lower than racing models, yet feature the same premium quality stainless steel forgings, Chrome stems, stellite tips, and swirl-polishing. If you do not see a valve you need in the Competition or Silverline Series, use the Portflow, as they are suitable for these applications.
Quicksilvers feature increased undercut stems and thicker margins for increased flow and performance.

Black Knight Series Stainless Valves

"Black Knight" (code: BK) feature a special coating that serves two purposes. First, the coating is designed to provide improved heat transfer. This promotes better valve train life. Secondly, the coating has proven to combat the problems associated with unleaded gasoline. In short, the Black Knight is what street performance enthusiasts have been waiting for! Black Knight valves are made in limited production runs and special ordering may be required. Carbon build-up is almost non-existent. Many available with single groove (code SGB). Fully swirl polished with Stellite tips.

Competition Series Valves Stainless Valves

This model features and undercut stem in the head area. In addition to reducing the valve weight (which provides benefits in opening rate and RPM limits) the radius of the head is such that it significantly improves air/fuel flow. This model enjoys great success when used with stock heads, as well as modified versions. Fully swirl polished. Chromed stems and Stellite tips.
Ideal for tough racing applications of all kinds. Now available for imports.

Silverline Series Stainless Valves

We are pleased to now offer upward extension of our existing product line with the addition of "The Silver Line". These premium quality racing valves are the perfect compliment to our current stock, street performance and competition valves. These new "Silver Line" valves compare favorably with top-of-the-line models from the competition in both appearance and performance. So there's no need to go anywhere else. Ideal for the most extreme racing conditions. Applications for aftermarket heads start at .050 longer. These are fully swirl polished. Chromed stems and Stellite tips. 21-4N EV8. Special thick margins and modified radius, make Silverlines the lightest and best flowing valves. Silverlines are available in hundreds of sizes for all types of serious race heads. You save money and get the best at the same time.
Compare the Silverline Series to anybody's best valve.
