20-2066 KPMI, exhaust valve guide. C630. +.006"

Designed for 1979 to 1984 80-inch Shovelhead models, this Kibblewhite exhaust valve guide is the solution for heads with worn guide bores that require a +.006 inch oversize for a proper press fit. It is constructed from C630 nickel-aluminum-bronze, a material typically reserved for high-performance and racing applications where heat dissipation is a primary concern. By moving heat away from the exhaust valve more effectively than iron, these guides help maintain engine health during hard riding. The standard non-oversize dimensions for these guides are 0.6250 inch outer diameter, 0.3745 inch inner diameter, and 1.91 inch overall length. Sold individually, they provide a durable, high-strength foundation for a performance Shovelhead top-end rebuild.
