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 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.

or brush.
2. Check valve face for excessive runout, pitting, and
burnt spots.

blocks and measure with a dial indicator.
4. Check the end of the valve stem for flaring, pitting,
wear or damage.
5. Inspect split keeper groove for wear or flaring in the
keeper seat area.
