Cylinder Head: Overview
- Clean gasket mating surfaces. Clean carbon from combustion chambers. Use care not to damage surfaces. Check cylinder head for cracks and warpage. Inspect gasket surface for burrs and nicks.
- If warpage exceeds .003" (.08 mm) in a 6" (152 mm) area, machine surface cylinder head. Do not machine surface more than .010" (.25 mm) from the original cylinder head gasket surface. Replace cylinder head as necessary.
