Installation Notes and Tips

Confirm the engine’s gasket thickness and bore diameter before installation. Clean and inspect the cylinder head and block sealing surfaces carefully, and verify that the right-side orientation matches the vehicle service position. Follow the manufacturer’s torque sequence, torque values, and any required head bolt replacement procedures during assembly.
