Good To Know

Q: How many valve guides does one head need? A: Count the valves in the head you are servicing, because each valve position uses its own guide. Match the quantity to your cylinder head before ordering.

Q: Does this valve guide need reaming after install? A: Follow your service manual for guide height and clearance, since some builds call for reaming or honing after pressing. Checking clearance before assembly avoids binding.

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