29. Place new O-rings (lightly coated with oil) onto each
of the head cap screws. Place four of these cap
screws (from opposite end of each other) into the
cylinder head. Thread the spark plugs in part way;
then while holding the head above the cylinder, care-
fully start and finger-tighten all four cap screws
while observing the cylinder O-rings to make sure
they remain in position. Slowly place the head into
position on top of the O-rings.

NOTE: To install the remaining cap screws, the
spark plugs must be removed.
30. Start and finger-tighten the cap screws being very
careful not to move the cylinder head; then tighten
the cap screws in two steps to 13 ft-lb then 28 ft-lb
using the pattern shown.
