KPMI cast iron valve guides are manufactured from a proprietary, custom-blended cast iron material formulated for high-demand engine environments. Specially balanced with carbon, silicon, manganese, nickel, chromium, copper, and sulfur, the metal forms a dense, fine-grained pearlitic microstructure that delivers exceptional wear resistance.

Designed for intake and exhaust positions on classic 45" Flathead engines, this replacement guide provides reliable dimensional stability and smooth valve movement. It offers high-precision fitment to restore optimal valvetrain geometry and long-lasting engine performance.
