Common questions
Will this valve guide fit my 1970 Shovelhead?
Yes, this guide is designed to fit Shovelhead models from 1966 through 1977. Always verify your specific engine build specifications before ordering.
Is this guide for the intake or exhaust valve?
This KPMI part is specifically for the intake valve position. Exhaust valve guides for these engines are a separate component.
What does '+0.006 oversize' mean for installation?
The +0.006 inch oversize bore is intended for cylinder heads where the original guide bore has worn larger than stock. It ensures a tight fit without further machining of the head, provided the wear is within this tolerance. Professional installation using a press or driver tool is recommended.
