Cylinder head bolts are not included and replacement is recommended for torque-to-yield applications. Clean all mating surfaces thoroughly, inspect the cylinder head for warpage, and follow the factory torque sequence and angle specifications during installation. Verify that all related sealing surfaces are free of debris before final assembly.
