   Ferrea Competition Plus Hollow Stem Valves
Chevy / Chrysler / Ford

One important factor to take into consideration to increase the engine’s rpm’s, is the valvetrain weight. Of course, the valve being a main component, the design has to be perfected to accomplish the weight reduction to allow higher rpm’s.

Ferrea’s latest contribution to this area is the introduction of its Lightweight Hollow Stem Valves. Ferrea has developed a manufacturing process that gun drill and micro polish the stem to achieve a valve reduction in weight of 20 percent compared to a conventional stainless steel solid stem valve. The valves also feature friction welded tips, radial grooves, avionics chrome plated stems, seat hardness up to 42 HRc and super flo to improve flow design.

Competition Plus Valve Highlights:
Friction welded tips
Avionics chrome plated stems
 Reduction in weight of 20 percent (vs. stainless steel solid stem)
