20-2054C KPMI, intake valve guide. Cast iron. +.004"

These Kibblewhite intake valve guides are the go-to choice for mechanics rebuilding late-model Shovelheads. Machined from high-quality cast iron, they offer the kind of durability and wear resistance required for heavy touring use. This guide is +.004 inch oversize, providing the extra material needed to achieve a proper interference fit in 1979 to 1984 80-inch (1340cc) Shovelhead cylinder heads. Cast iron remains the standard for longevity in air-cooled engines, helping to pull heat away from the valve stem while providing a stable, low-friction guide path. If you are looking to restore factory-level reliability to your valvetrain, these precision-machined guides are a solid investment for your rebuild.
