Cylinder Head Height & Flatness Check
- Measure cylinder head mounting surface diagonally. If cylinder head is warped more than .001" (.05 mm) it must be surfaced. After machining, measure overall thickness of cylinder head. Remove all attachments when grinding cylinder head. DO NOT grind more than 0.010" (0.25 mm).
- Ensure cylinder head thickness exceeds minimum cylinder head thickness. See CYLINDER HEAD under ENGINE SPECIFICATIONS.
NOTE:
A .012" (0.30 mm) cylinder head gasket is available for machined cylinder heads.
