Specs At A Glance

Good To Know

Q: Should head bolts be replaced at the same time? A: Many torque-to-yield head bolts are single-use, so check your service manual and replace them if spec calls for it. A: Reusing stretched bolts can cause uneven clamping and a repeat gasket failure.

Q: Is surface preparation important before install? A: Yes, both the head and block decks should be clean, flat, and free of old gasket material. A: Any warp or debris left behind can cause the new head gasket to leak.

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