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

This .002-inch oversize exhaust valve guide from Kibblewhite is specifically designed for 1979 to 1984 80-inch (1340cc) Shovelhead models. If your cylinder head guide bores have been enlarged or cleaned up during a previous rebuild, this oversize manganese bronze guide ensures a proper interference fit. Manganese bronze is favored for its rapid heat transfer and excellent lubricity, which are critical for exhaust valve longevity. These guides are notably easier to ream to final size than C630 bearing bronze, making them a favorite for shops using simple finishing tools. It is a durable, budget-friendly solution for maintaining proper valve geometry in classic Shovelhead engines.
