General Specifications
Cylinder head gasket surface flatnessNOTE: Use a straight edge that is calibrated by the manufacturer to be flat with 0.005 mm (0.0002 inch) per running foot length. For example, if the straight edge is 61 cm (24 inch) long, the machined edge must be flat with 0.010 mm (0.0004 inch) from end to end.
Using a straight edge and a feeler gauge, inspect the cylinder head for flatness in the sequence shown. If the cylinder head is distorted, install a new cylinder head.
