Cylinder Head Assembly: Testing and Inspection

1. Check the cylinder head gasket surface for flatness by using a straightedge and thickness gauge. The standard value is 0.05 mm (0.0020 inch) and the limit is 0.2 mm (0.008 inch).
2. If the service limit is exceeded, correct to meet specification. The grinding limit is 0.2 mm (0.008 inch), (combined with cylinder block grinding).
3. The cylinder head height (specification when new) is 119.9 - 120.1 mm (4.720 - 4.73 inch).
