Good To Know

Q: Do I need to replace all valve guides at once? A: Replacing the full set during a top-end rebuild is common practice since wear tends to be similar across guides. Confirm the correct quantity for your engine before ordering.

Q: Does this guide fit both intake and exhaust sides? A: This guide is listed for either intake or exhaust valve positions as noted in the listing. Verify your specific cylinder head application before installation.

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