Note: the I.D.s of the guides are intentionally made small and require honing by your machinist to match the stems of your specific valves because very tight clearances are required for optimum performance.

Intake: 1-1.5 thousandths larger than valve stem O.D.
Exhaust: no less than 1.5 thousandths larger than valve stem O.D.
