Good To Know

Q: Do I need to ream or hone the guide after installation? A: Valve guides are normally sized after pressing in, so have the head machined by a shop that can set stem clearance to spec. Skipping this step can cause sticking valves or oil consumption.

Q: Can I use this guide in both intake and exhaust positions? A: Yes, this guide fits either position on the listed 1503 head. Order the quantity your specific head service requires.

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