Installation Notes and Tips

Review the fitment notes before installation: exhaust pipe gasket not included, cylinder head bolts not included, and cylinder head bolt replacement is recommended. Because this application is torque-to-yield, follow the correct tightening sequence and torque procedure for the engine. Confirm all mating surfaces are clean and flat before assembly.
