Common questions
What does +0.002 oversize mean?
The guide has an outer diameter that is 0.002 inches larger than the standard size. This requires the cylinder head bore to be reamed or machined to match the oversized guide for a correct press fit.
Will this fit my 1966 Shovelhead?
Yes, this KPMI intake valve guide is compatible with all Harley-Davidson Shovelhead engines from 1966 through 1977, as well as Panhead engines from 1948-1965.
Is this for an intake or exhaust valve?
This part is an intake valve guide only. If you need exhaust guides, you will need to order the corresponding exhaust part number separately.
