Installation is the same as for original equipment cylinder heads. Consult
service manual for specific procedures, if necessary. Be sure that the
surface of the block and the surface of the head are thoroughly cleaned
to remove any oily film before installation. Use alcohol or lacquer thinner
on a lint-free rag to clean. Apply oil or suitable thread lubricant to head
bolt threads and the underside of bolt heads and washers to prevent
galling and improper torque readings. Use thread sealant on any bolts
that go into coolant passages. Torque top row of bolts to 110 ft./lbs. and
bottom row of bolts to 100 ft./lbs. in three or four steps, following the
factory tightening sequence
(See Figure 1)
.
A re-torque is
recommended after the initial star-up and cool-down (allow 2-3 hours for
adequate cooling).
INSTALLATION PROCEDURE
Figure 1 - Buick Cylinder Head Bolt Torque Sequence
Torque Top Row of Bolts to 110 ft./lbs.
Torque Bottom Row of Bolt s to 100 ft./lbs.
(Torque Bolts in 3 to 4 steps, gradually approaching final torque spec)
Other Assembly Tips:
When installing the sparkplugs and exhaust
manifolds, be sure to use a high temperature anti-seize compound on the
threads to reduce the possibility of thread damage in the future. Do not
exceed a torque of 25 ft./lbs. on the intake manifold bolts and lubricate
the bolt threads prior to assembly.
NOTE: Torque sparkplugs to 10 ft./lbs. Do not over tighten
sparkplugs! If short reach plug is used, poor performance and
possible engine damage may occur.
