Common questions
What does +0.002 inch oversize mean for this valve guide?
This guide is manufactured with a bore 0.002 inches larger than stock. It's designed for cylinder heads where the original valve guide bore has worn larger and requires machining to this oversize spec for a tight fit.
Is this valve guide for intake or exhaust valves?
This KPMI valve guide is specifically for the exhaust valve position on Panhead and Shovelhead engines. You will need to order intake guides separately if both are being replaced.
Will this part fit my Evolution or Twin Cam engine?
No, this KPMI valve guide is designed exclusively for Harley-Davidson Panhead (1948-1965) and Shovelhead (1966-1977) engines. It is not compatible with later Evolution or Twin Cam platforms.
