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

This Kibblewhite exhaust valve guide is a .006-inch oversize version intended for 1979 to 1984 80-inch (1340cc) Shovelhead models. When a standard or small-oversize guide just won't stay tight, this .006-inch option provides the necessary diameter to restore the cylinder head. Made from manganese bronze, it ensures rapid heat transfer away from the exhaust valve stem while providing excellent lubricity. This material is specifically chosen for its ease of machining, allowing for quick reaming and finishing with simple workshop tools. It is a reliable and cost-effective way to ensure your Shovelhead's valve train remains stable and properly aligned for miles to come.
