NOTE:
Make sure all cylinder head surfaces are clear of
any gasket material, silicone sealant, oil and coolant. The cylinder
head surface must be clean and dry before running a flatness check.
NOTE:
Use a Straightedge that is calibrated by the
manufacturer to be flat within 0.005 mm (0.0002 in) per running foot of
length, such as Snap-On® GA438A or equivalent. For example, if the
Straightedge is 61 cm (24 in) long, the machined edge must be flat
within 0.010 mm (0.0004 in) from end to end.
Using a Straightedge and a Feeler Gauge Set, inspect the cylinder head for flatness in the sequence shown.
