Good To Know

Q: Can this guide be used on either valve position? A: Yes, it is listed for both intake and exhaust sides, so one part number covers both locations. Confirm the bore size needed for your specific cylinder head before pressing it in.

Q: Does replacing a valve guide require machining? A: Valve guides are normally pressed into the head and often reamed or honed to final clearance. Many shops measure the stem-to-guide clearance after installation to verify the fit.

Slight variation in finish or dimensions may occur between production runs, and fit can depend on serial number, so confirm compatibility before ordering.
