Cylinder Head Inspection
Thoroughly clean cylinder head surface to remove all
traces of gasket material and carbon.
CAUTION
Use care not to damage gasket sealing surface. All
gasket surfaces must be clean, dry and free of any oil
or grease upon assembly. Clean sealing surfaces with
rubbing alcohol or electrical contact cleaner. Do not
touch sealing surfaces of the new head gasket.
Cylinder Head Warp Inspection
1. Lay a straight edge (1) across the surface of the
cylinder head at several different points and measure
warp by inserting a feeler gauge between the straight
edge and the cylinder head surface. If warp exceeds
the service limit, replace the cylinder head.
