20-2056 KPMI, intake valve guide. C630. +.006"

When a Shovelhead head has been through several rebuilds, you often need a larger guide to get the right interference fit. This Kibblewhite intake valve guide features a +.006 inch oversize outer diameter, designed specifically for 1979 to 1984 80-inch 1340cc models. It is manufactured from C630 nickel-aluminum-bronze, a tough alloy that excels at heat dissipation in high-performance and racing scenarios. For reference, the standard dimensions are 0.6250 inch outer diameter, 0.3745 inch inner diameter, and 1.91 inch overall length. Sold individually, these guides help maintain critical valvetrain alignment while protecting against the excessive heat that can plague air-cooled V-twins during spirited riding or competition use.
