20-2056M KPMI, intake valve guide. Manganese. +.006"

This KPMI intake valve guide is designed for 1979 to 1984 80-inch 1340cc Shovelhead models that require a +.006-inch oversize outer diameter. This extra material is crucial for heads with worn guide bores, ensuring a proper press fit and stable valve operation. The manganese bronze construction provides excellent thermal conductivity and lubricity, which helps prevent valve stem wear and ensures smooth engine performance. This material is particularly easy to ream and hone, allowing you to achieve precise clearances with basic shop tools like a ball hone and an electric drill. Sold individually, this guide is a reliable and economical choice for restoring the top end of your late-model Shovelhead engine.
