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 rod springs.
Tighten the bolts to the
high side of the torque
specification, but do not exceed
the limit or the bolts may
stretch beyond their elastic
limits.
Attempting to tighten the
bolts in one step may result
in trouble and consequent loss
of time in diagnosis 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.
