Kibblewhite KPMI Cast Iron Exhaust Valve Guide +.008 Precision-machined from a proprietary cast iron blend, this valve guide is engineered for durability and high performance. Kibblewhite specifies the composition of their cast iron, including elements such as carbon, silicon, manganese, nickel, chromium, copper, and sulfur, to achieve a highly pearlitic structure with dense fine grains, ensuring excellent wear resistance. Designed to be compatible with no-lead fuel, this guide can accommodate any type of valve-stem material. KPMI valve guide profiles are optimized to minimize airflow disruption while maintaining critical cross-sectional thickness in high-temperature areas, promoting both endurance and performance. Precision machining ensures strict adherence to ID/OD tolerances and cylindricity specifications.
