Competition Plus Hollow Stem Exhaust Valves by Ferrea

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

Ferrea’s latest contribution in this area is our Lightweight Hollow Stem Valves. Ferrea has developed a proprietary manufacturing process that gun drills and micro polishes the bore of a valve stem. This proprietary process insures greater structural integrity than any hollow valve on the market today. This achieves a valve reduction in weight of approximately 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 42HRc and Super Flo designs to improve flow.
