3. Position new seals on the cyl-
inder block and new gaskets on the
cylinder heads, with the gaskets inter-
locked with the seal tabs. Be sure the
holes in the gaskets are aligned with
the holes in the cylinder heads.
Apply non-hardening sealer at the
four junction points of the gaskets
and seals.
4. Carefully lower the intake man-
ifold into position on the cylinder
block and cylinder heads.
After the
intake manifold is i n place, run a
finger around the seal area to make
sure the seals are in place. I f the
seals are not i n place, remove the in-
take manifold and position the seals.
5. Be sure the holes in the mani-
fold gaskets and manifold are in
alignment. Using new sealing wash-
ers, install the intake manifold retain-
ing nuts and bolts. Torque the nuts
and bolts in two steps. Torque in
sequence to specifications.
After completing the remaining
assembly stips, operate the, engine
until i t reaches normal operating
temperature, then retorque the mani-
fold nuts and bolts in sequence to
specifications.

6. Install the watei pump by-pass
hose on the coolant outlet housing.
Slide the clamp into position and
tighten the clamp.
7. Connect the radiator upper.
hose. Install the heater hose against
the automatic choke housing and
connect the hose at the intake mani-
fold.
8. Install the carburetor fuel in-
let line and the automatic choke heat
tube.
9. Rotate the crankshaft damper
until the No. 1 piston is on TDC at
the end of the compression stroke.
Position the distributor in the block
with the rotor at the No. I firing
position and the points open. Install
the hold down clamp.
10. Install the distributor cap, Po-
sition the spark plug wires in the
harness brackets on the valve rocker
arm covers, and connect the spark
plug wires.
11. Connect the crankcase vent
hose. Connect the high tension lead
and coil wires.
12. Connect the accelerator rod
and retracting spring.
On a vehicle equipped with vac-
uum operated accessories, connect
any vacuum lines that were discon-
nected from the intake manifold dur-
ing removal.
On a vehicle with air conditioning,
install the compressor to intake man-
ifold brackets.
13. On Thermactor engines, con-
nect the hose from the left air mani-
old to the air bypass valve.
14. Fill and bleed the cooling sys-
tem.
15. Start the engine and check
and adjust the ignition timing. Con-
nect the distributor vacuum hoses to
the distributor.
16. Operate the engine at fast idle
and check all hose connections and
gaskets for leaks. When engine tem-
peratures have stabilized adjust the
engine idle speed and idle fuel mix-
ture. Retorque intake manifold bolts
to specifications.
17. Connect the automatic choke
heat chamber air inlet hose.
18. Install the air cleaner and in-
take duct assembly.
