These Hollow Stem Lightweight Valves are manufactured with a unique process that gun drill and micro polish 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 allow engines to run at higher rpm’s than comparable solid valves in classes that do not allow the use of titanium valves.
