Ferrea LS7 Hollow Stem Exhaust Valve
Ferrea LS7 Hollow Stem Exhaust Valves
These Hollow Stem Lightweight Valves are manufactured with a unique process that gun drills and micro polishes the hollow stem cavity. These valves achieve a weight reduction of approximately 20 % in a small block compared with a conventional stainless steel solid-stem valve. This weight savings allows engines to run at higher rpm than comparable solid valves in classes that do not allow the use of titanium valves.
