Installation Notes and Tips

Professional engine assembly practices are recommended. Verify block or cylinder head compatibility before installation, especially for applications noted as w/o “T” on engine block. Clean all oil passages thoroughly, inspect camshaft journals, and confirm bearing alignment and clearance during assembly. Fitment includes Chevrolet, GMC, Oldsmobile, Isuzu, and Pontiac applications; review the vehicle-specific notes carefully before ordering.
