The 5 percent nickel content provides superior resistance to wear, and the 80 percent copper content delivers outstanding heat conductivity. Guide profiles are designed to have minimal effect on the airstream while maintaining critical cross sectional thickness in high temperature areas, promoting high performance and endurance. The top portion of the guides are shortened when cam lift information available at the time of design shows that additional retainer to seal clearance is required. KPMI® Bronze Valve Guides: C674 Bronze Guide. These Engine Builder valve guides have been designed with the price conscious builder in mind. Expect the same exacting KPMI® tolerances, but with a reduced toughness / wear-ability when compared to premium C630 Nickel Aluminum Bronze valve guides. The softer Manganese guides are easily reamed, and then can be delicately finished with our high quality ball hones. Now, with any battery operated or electric drill you can ream and hone manganese valve guides in less time and in the absence of expensive honing equipment required to properly size tough Nickel Bronze guides. KPMI® Tappets: KPMI® engineers design our tappets using advanced finite element stress analysis software. This software allows our engineers to lighten the tappets without sacrificing strength, so we can create the strongest, lightest tappets possible. These tappets are machined from aircraft quality solid steel bar stock. They undergo a proprietary heat treatment process that creates a hard surface and a non-brittle core, maximizing toughness and wear resistance. KPMI® tappets are run in high performance automotive and motorcycle racing applications including Motocross, Flat Track Racing, Road Racing, Drag Racing, and Land Speed Racing at the Bonneville Salt Flats.
