Common questions
What does '+0.002 oversized' mean?
The +0.002 inch oversized bore means this guide is slightly larger than a standard guide. It's designed to fit cylinder head bores that have worn slightly, providing a snug fit without needing to machine the head to a larger oversize.
Is this valve guide for intake or exhaust applications?
This KPMI part is an intake valve guide only. If you need to replace exhaust guides, you will need to order them separately as they are a different part number.
Will this fit Shovelhead engines made before 1978?
This valve guide is specifically engineered for 1978-1983 Shovelhead models. Earlier Shovelhead engines may use different guide dimensions, so it's important to verify compatibility with your engine's build specifications before purchase.
