Of course, the valve being a main component, the design has to be perfected to accomplish the weight reduction to allow higher RPMs. Ferrea's latest contribution to this area is the introduction of its Lightweight Hollow Stem Valve. We developed a manufacturing process that gun drills and micro polishes the stem to achieve a valve reduction in
