or grease upon assembly. Clean sealing surfaces with
rubbing alcohol or electrical contact cleaner. Do not
touch sealing surfaces of the new head gasket.

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.
