from the cylinder head. Brace the as-
sembly so that the muffler inlet pipe
will not be damaged.
12.
Disconnect the radiator sup-
ply tank support at the water pump.
Loosen the supply tank hose clamp
at the coolant outlet housing and re-
move the supply tank.
13.

ing fixtures for convenience in lift-
ing the head and to protect the gasket
surfaces (Fig. 22).
14.

studs (Fig. 23). Lift the cylinder
head assembly off the engine. Do
not pry between the head and block
as the gasket surfaces may become
damaged.
INSTALLATION
1.
Clean the head and block gas-
ket surfaces .
2.
If the cylinder head was re-
moved for a cylinder head gasket re-
placement, check the flatness of the
head and block gasket surfaces (Part
1-1).
3.
Position the gasket over the
guide studs on the cylinder block.
4.

6. Install, but do not tighten, two
bolts at opposite ends of the head to
hold the head and gasket in position.
7.
Remove the guides. Remove
the cylinder head holding fixtures. In-
stall the remaining bolts.
8. The cylinder head bolts are
tightened in three progressive steps.
Follow the sequence shown in Fig.
24.
Torque the bolts to 95 ft-lbs,
then to 105 ft-lbs. Finally, torque the
bolts to 115 ft-lbs.
9. Apply Lubriplate to both ends
of the push rods. Install the push rods
in their original bores, positioning
the lower end of the rods in the tap-
pet sockets.
10.
Install the valve rocker arm
shaft assembly by following steps 1
thru 5 under "Valve Rocker Arm
Shaft Installation."
11.
Position the radiator supply
tank and connect the hose at the
coolant outlet housing. Position the
generator adjusting arm and radiator
supply tank support and install the
retaining bolt.
12.
Clean the intake manifold gas-
ket surfaces. Install new intake mani-
fold gaskets using new sleeves, if
necessary, in the ports of the cylinder
head. Place the manifold assembly in
position against the head. Make sure
none of the gaskets have become
dislodged.
13.
Install the manifold assembly
retaining lock washers and bolts (two
manifold bolts retain the radiator
supply tank mounting bracket and
one bolt retains the oil level dipstick
tube bracket). Torque the bolts to
specifications.
14.
Connect and adjust the choke
control cable.
15.
Position the fuel inlet line and
the vacuum line on the engine. Con-
nect the distributor vacuum line and
the carburetor fuel inlet line at the

and the coil high tension lead.
19.
Connect the carburetor fuel
inlet line at the fuel pump, and the
distributor vacuum line at the dis-
tributor.
20.
Connect the battery ground
cable. Connect the water tempera-
ture sending unit wire.
21.
Connect the radiator upper
hose at the radiator. Connect the
heater hose at the water outlet hous-
ing, but do not tighten the clamp.
22.
Fill and bleed the cooling sys-
tem. Adjust the valves (Part 1-1). In-
stall the valve rocker arm cover by
following step 6 under "Valve Rocker
Arm Shaft Assembly Installation."
23.
Operate the engine until en-
gine temperatures have stabilized.
24.
Adjust the engine idle speed
and idle fuel mixture. Install the air
cleaner.
On a car with an automatic trans-
mission, adjust the transmission con-
trol linkage.
DISASSEMBLY
1.
Remove the coolant outlet hous-
ing and thermostat. Discard the
gasket.
2.
Remove the temperature send-
ing unit from the head.
3.
Remove deposits from the com-
bustion chambers and valve heads
with a scraper and a wire brush be-
fore removing the valves. Be care-
ful not to scratch the cylinder head
gasket surface.
4.
Compress the valve springs (Fig.
25),
then remove the valve retainer
locks and release the spring.
