Installation Notes and Tips

Clean all mating surfaces thoroughly before installation and verify flatness of the cylinder head and block. Because this application uses torque-to-yield fasteners, replace the cylinder head bolts during service even though they are not included. Follow the vehicle-specific torque sequence and tightening procedure exactly, and confirm all related seals and surfaces are ready before reassembly.
