Installation Notes and Tips

Confirm engine code, bore size, and thickness before installation. The fitment notes specify cylinder head bolt replacement, and torque-to-yield fasteners should be replaced during service. Clean both sealing surfaces thoroughly and follow the manufacturer’s torque sequence and angle specifications during assembly. Verify that the replacement gasket matches the application before final engine reassembly.
