Good To Know

Q: Do I need different guides for intake and exhaust valves? A: This listing covers the intake or exhaust valve guide for the 1503 head, so confirm which position you are replacing. Checking the service manual for the correct position helps you order the right quantity.

Q: Can a valve guide be replaced without removing the cylinder head? A: Valve guide replacement normally requires cylinder head removal along with the valves and springs. Having the head off the engine is the standard way to press out the old guide and install the new one.

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