Common questions
What does +0.004 oversize mean for this valve guide?
This indicates that the valve guide's outer diameter is 0.004 inches larger than the standard size. This is used when the valve guide bore in the cylinder head has worn beyond what a +0.002 guide can correct, requiring more material for a precise hone.
Is this valve guide for the intake or exhaust side?
This KPMI part is an exhaust valve guide. Intake valve guides are different and must be ordered separately if needed for your rebuild.
Will this fit all Shovelhead models?
This valve guide is specifically designed for Harley-Davidson Shovelhead engines from 1978 to 1983. Please verify your engine's year and model for correct fitment.
