20-2052 KPMI, intake valve guide. C630. +.002"

This Kibblewhite intake valve guide is the ideal upgrade for 1979 to 1984 80-inch Shovelhead owners looking for better thermal performance. Made from C630 nickel-aluminum-bronze, this guide is designed to dissipate heat much faster than standard iron, making it perfect for high-performance or racing applications. This particular version is machined to a +.002 inch oversize outer diameter to accommodate cylinder heads with slightly worn guide bores. The standard reference dimensions are 0.6250 inch outer diameter, 0.3745 inch inner diameter, and 1.91 inch overall length. Sold individually, these bronze guides provide a durable and high-strength solution for maintaining valvetrain geometry under extreme conditions, ensuring your 1340cc Shovelhead runs cooler and lasts longer.
