These valves are intended as O.E.M. replacement valves and are completely compatible with the O.E.M. spring kits. However, experienced engine builders, who
are running aggressive camshafts or higher than factory RPM’s may 昀椀nd the combination of the O.E.M. Style Valve and KPMI’s Lightweight Racing Spring Kits
advisable. All titanium valves are (Tensilite®) PVD CrN coated, and all stainless valves are Black Diamond™ coated.
