High Performance Kibblewhite Intake or Exhaust Valve Guide (Standard Size). Made in the USA by Kibblewhite who have been making High Quality Performance parts for 75+ years.
Kibblewhite uses the copper based C63000 nickel-aluminum bronze as a material to make these bronze valve guides because of its ideal characteristics for the application. The 5% nickel content provides superior resistance to wear, and the approximately 80 percent copper content delivers outstanding heat conductivity. Kibblewhite guide profiles are designed to have minimal effect on the airstream while maintaining critical cross sectional thickness in high temperature areas, which promotes high performance and endurance.
