installing

Note:

Replace cylinder head bolts.
Always replace self-locking nuts, bolts as well
as gaskets and O-rings.
After installing a replacement cylinder head with
camshafts attached, grease contact surfaces
between valve lifters and cam lubricating
surfaces.
Do not remove plastic covers protecting
exposed valves until immediately before
installing cylinder head.
When replacing the cylinder head or cylinder
head gasket, coolant must be completely
replaced.
Cylinder heads with small cracks between the
valve seats that are less than 0.3 mm (0.012
in.) wide and/or between one valve seat and
only the first 4 threads of the spark plug thread,
can continue to be used without reduced
service life.
