Good To Know

Q: Does this valve guide fit both intake and exhaust positions? A: Yes, this guide is designed to serve either the intake or exhaust valve position on the 1503 engine.

Q: Can I install this without machining the cylinder head? A: Valve guides are typically pressed in and may require reaming to final clearance, so a machine shop is recommended for proper fit.

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