e. Install damper retaining bolt and torque to
specifications.
9. Install cylinder head(s) as follows:
CAUTION: The gasket surfaces on both the
head and the block must be clean of any
foreign matter and free of nicks or heavy
scratches. Cylinder bolt threads in the block
and threads on the cylinder head bolts must be
cleaned. (Dirt will effect bolt torque).
a. On engines using a STEEL gasket, coat both
sides of gasket with sealer, spread the sealer thin
and even. Too much sealer may hold the beads
of the gasket away from the head or block. One
method of applying the sealer that will assure
the proper coat is with the use of a paint roller.
CAUTION: Use no sealer on engines using a
composition STEEL ASBESTO S gasket.
b. Place the gasket in position over the dowel pins,
with the bead up.
c. Carefully guide cylinder head into place over
dowel pins and gasket.
d. Coat threads of cylinder head bolts with sealing
compound and install finger tight.
e. Tighten cylinder head bolts a little at a time in
torque sequence shown in Figure 77 until the
specified torque is reached. (See Engine
Torques.)
NOTE: All engines using composition STEEL
ASBESTOS gaskets must have the cylinder
head retorqued after engine warm-up.

Disassembly
1. With cylinder head removed, remove valve rocker
arm nuts, balls and rocker arms (if not previously
done).
2. Using Tool J-8062, compress the valve springs (fig.
13) and remove valve keys. Release the compressor
tool and remove rotators or spring caps, spring
shields (if so equipped) springs and spring damper,
then remove oil seals and valve spring shims.
3. Remove valves from cylinder head and place them
in a rack in their proper sequence so that they can
be assembled in their original positions.
