20-2062 KPMI, exhaust valve guide. C630. +.002"

This Kibblewhite exhaust valve guide is designed for the 1979 to 1984 80-inch Shovelhead and is manufactured from C630 nickel-aluminum-bronze. This high-performance material is much tougher than standard iron and is engineered to pull heat away from the exhaust valve stem quickly, which is vital for high-output or racing engines. This guide features a +.002 inch oversize outer diameter for a secure fit in heads with slightly enlarged bores. Standard reference dimensions are 0.6250 inch outer diameter, 0.3745 inch inner diameter, and 1.91 inch overall length. Sold individually, these bronze guides are a premium upgrade for any Shovelhead rider looking to improve valvetrain reliability and cooling efficiency during heavy-duty use.
