20-2054M KPMI, intake valve guide. Manganese. +.004"

For 1979 to 1984 80-inch 1340cc Shovelhead owners, this KPMI intake valve guide is an essential part for a quality top-end rebuild. This guide features a +.004-inch oversize outer diameter, providing the necessary material for heads with worn or slightly oversized guide bores. Manganese bronze is used for its excellent thermal conductivity and lubricity, helping to keep intake valve temperatures under control. While it is a more budget-friendly option than C630 bearing bronze, it is highly effective and much easier to machine. You can easily ream it to size and finish it with a simple ball hone and an electric drill. Sold individually, this guide is a reliable solution for restoring proper valve-to-guide clearance.
