20-2051M KPMI, intake valve guide. Manganese. +.001"

When you are rebuilding a 1979 to 1984 80-inch 1340cc Shovelhead, these KPMI manganese bronze intake valve guides are an excellent choice. This version features a +.001-inch oversize outer diameter, providing a perfect press fit for cylinder heads that have been lightly cleaned or honed. Manganese bronze provides superior heat dissipation and natural lubricity for the valve stem, ensuring smooth operation. It is also much easier to ream and hone than harder bronze alloys, allowing you to achieve precise clearances with standard shop tools like an electric drill and a ball hone. Sold individually, these guides offer a great balance of performance and ease of installation for your late-model Shovelhead restoration.
