20-2052M KPMI, intake valve guide. Manganese. +.002"

This Kibblewhite intake valve guide is a precision component for 1979 to 1984 80-inch 1340cc Shovelhead engines. It features a +.002-inch oversize outer diameter to ensure a tight, secure fit in cylinder heads where the original guide bores have become slightly enlarged. Cast from manganese bronze, this guide excels at transferring heat away from the intake valve and provides excellent lubricity to prevent stem wear. Mechanics prefer this material because it is easy to ream to size and can be finished with basic shop tools like a ball hone and an electric drill. Sold individually, this guide is a smart and cost-effective choice for maintaining the performance and reliability of your late Shovelhead's valve train.
