Installation Notes and Tips

Confirm engine code and gasket layout before installation. Because this set is torque-to-yield related, replacement cylinder head bolts are recommended where the service procedure calls for them, and the listing notes that bolts are not included. Clean all mating surfaces thoroughly, inspect the cylinder head for warpage, and follow the factory torque sequence and angle specifications during assembly. Verify all coolant, oil, and intake sealing surfaces before final startup.
