Detailed Description

Installation Notes

Confirm engine serial number and cylinder head dowel size before ordering, since fitment notes specify 20 mm cylinder head dowels and serial-number breakpoints. Cylinder head bolts are not included, and the fitment notes recommend bolt replacement. Follow the manufacturer’s torque sequence and torque-to-yield procedures during installation. Verify all sealing surfaces are clean and flat before assembly.
