Product Description
Features: Replaces the OEM valves and valve springs. Steel, nitrided valves for increased durability and less wear under extreme conditions. Stronger valve springs deal with the extra weight of the steel valves. Springs are made from premium chrome vanadium steel for higher performance and durability at high rpm. Kit contains a set of steel intake or exhaust valves plus a set of specially designed valve springs; can be installed using the OEM retainers, bases and valve seals.
