Common questions
Will this fit my Shovelhead with a stroker kit?
This is a standard OEM replacement guide. If your Shovelhead has been bored or stroked, verify the valve stem diameter with your engine builder before ordering to ensure compatibility.
Is this for intake or exhaust applications?
This is an intake valve guide only. KPMI offers separate exhaust guides if needed for your Shovelhead.
How do I know if my valve guides are worn?
Signs include excessive valve stem play, blue smoke on cold start, or increased oil burning. A machine shop can accurately measure valve stem clearance to confirm wear.
