Good To Know

Q: Does this gasket require new head bolts? A: Many 1503 head jobs call for new torque-to-yield bolts, so check your service manual before reassembly. Reusing stretched bolts can prevent proper clamping.

Q: Should the head and block surfaces be checked first? A: Yes, both surfaces should be clean and flat before fitting a new head gasket. Warped or pitted surfaces will cause leaks even with a fresh gasket.

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