Common questions
What does '+0.006 oversize' mean?
The +0.006 inch oversize indicates that the guide's bore is 0.006 inches larger than stock. This size is specifically intended for cylinder heads where the original valve stem holes have experienced significant wear, allowing for a proper fit without further head machining.
Will this fit a standard (non-oversize) Shovelhead cylinder head?
No, this +0.006 inch oversize guide is designed for cylinder heads that have worn valve stem holes. If your head has a standard, unworn bore, you would need a standard-sized valve guide. It is crucial to verify your head's condition before ordering.
Is this valve guide for intake or exhaust applications?
This KPMI part is an intake valve guide only. Exhaust valve guides for these Shovelhead models are a different part and must be ordered separately.
