Good To Know

Q: Is this guide for the intake side or the exhaust side? A: It is listed for use in either the intake or exhaust valve position, so verify the required guide against your machine's parts diagram before ordering. A: Correct valve stem clearance depends on proper installation and reaming, so have the head measured and fitted by a qualified machinist.

Q: How many should I order for one head? A: Order one guide for each valve position you are replacing, since this listing is for a single valve guide. A: Replacing guides is normally paired with new valve seals and a valve job for best results.

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