Kibblewhite’s manganese bronze guides deliver superior heat conductivity to keep valve temperatures in check, extending component life and maintaining precise valve sealing. Best of all, these guides machine easily with standard shop equipment—no exotic honing tools required.
The 20-20871M is precision-machined to OEM and aftermarket specifications, making installation straightforward for experienced machinists and engine builders.
