Installation Notes and Tips

Confirm engine code, cylinder head design, and the 14.4mm valve guide O.D. note on 2001 applications before ordering. Cylinder head bolts are not included, and bolt replacement is recommended for the listed vehicles because this is a torque-to-yield application. Clean and inspect all mating surfaces carefully before assembly, and follow the factory torque sequence and specifications for the engine.
