4. After the head is in place,
remove the guide studs and
install the remaining bolts.
5. Tighten the bolts to 175-185
lb-ft (238-251 Nm) torque,
one-half turn at a time, in
the sequence shown. Begin
on the cam follower side of
the head to take up tension
in the push rods springs.
Tighten the bolts to the high
side of the torque specifica-
tion, but do not exceed the
limit or the bolts may stretch
beyond their elastic limits.
Attempting to tighten the
bolts in one step may re-
sult in trouble and conse-
quent loss of time in diag-
nosis and correction of
difficulties, such as com-
pression leaks, when the
engine is put into operation.
NOTE
Tightening the cylinder head bolts will not correct a leaking
compression gasket or seal. The head must be removed and
the damaged gasket or seal replaced.
