The Kibblewhite Precision Machining Inc. (KPMI) Cast Iron Exhaust Valve Guide (+.002) is engineered for high performance and durability. Precision-machined from Kibblewhite's proprietary cast iron, it features a highly pearlitic structure with dense fine grains for excellent wear resistance. The material composition includes carbon, silicon, manganese, nickel, chromium, copper, and sulfur, ensuring compatibility with no-lead fuel and all valve-stem materials. Designed to minimize airflow disruption while maintaining critical cross-sectional thickness in high-temperature areas, this valve guide enhances both performance and endurance. It has an overall length of 1.90", with strict attention given to ID/OD tolerances and cylindricity for optimal fit and function.
