Good To Know

Q: How many valve guides does one engine need? A: A 1503 head uses multiple guides, so confirm the quantity your rebuild requires before ordering. Q: Can I install this without machine work? A: Guide installation typically requires pressing and reaming to the correct clearance, so professional cylinder head service is recommended.

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