Good To Know

Q: Should head bolts be replaced when installing this gasket? A: Many engine builders recommend new head bolts since torque-to-yield fasteners can stretch. Check the service manual for your specific engine before reuse.

Q: Does this gasket require any sealant during installation? A: Most head gaskets of this type install dry unless the service manual states otherwise. Follow the factory torque sequence and specs for a proper seal.

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