the engine and toward the front of the engine on the
left bank and to the rear of the right bank, making
sure to install the long stamped steel retainers in the
number two and four positions, tighten to 15 foot-
pounds.
(2) On 361, 383 and 426 Cubic Inch Engines only,
install the rocker shafts so that the
3/16
inch diam-
eter rocker arm lubrication holes point downward into
the rocker arm, and so that the 15" angle of these
holes point outward towards the valve end of the
rocker arms (See Fig. 66).
NOTE: The 15O angle of the rocker arm lubrica-
tion holes is determined from the center line of the
bolt holes through the shaft which are used to at-
tach the shaft assembly to the cylinder head.
(3) Install the rocker arms and shaft assembly mak-
ing sure to install the long stamped steel retainers in
the number two and four positions.
NOTE: Use extreme care in tightening the bolts so
that tappets have time to bleed down to their oper-
ating length. Bulged tappet bodies, bent push rods
and permanent noisy operation may result if the
tappets are forced down too rapidly.
(4) Tighten the bolts to 25 foot-pounds torque.
(5) On 273 and 318 Cubic Inch Engines only, start
the engine and run until normal operating tempera-
ture is reached.
(6) Adjust the tappets to .013 inch for intake and
.021 for exhaust.
(7) Install the valve covers with new gaskets, tight-
en to
40
inch pounds torque.

(2)
Disconnect the throttle linkage, coil wires, heat
indicator sending unit wire and heater hoses at the en-
gine.
(3) Remove the distributor cap and the spark plug
cables and the engine closed vent system.
(4) Remove the intake manifold attaching bolts and
remove the manifold, carburetor and coil as an as-
sembly.
(5) On
361, 383, and 426 Cubic inch engines
only,
remove the tappet chamber cover and spark plugs lo-
cated under the exhaust manifolds.
(6) Remove the cylinder head covers, closed vent
system and exhaust manifolds. (All engines.)
(7) On
273, 361, 383 and 426 Cubic inch engines
only, remove the rocker arms and shaft assemblies,
push rods and place them in their respective slots in
holder, Tool C-3068.
(8) Remove head bolts from each cylinder head and
remove cylinder heads. Place cylinder heads in hold-
ing fixture, Tool C-3626.
NOTE: The 318 Cubic Inch Engine push rods are
removed with cylinder head and rocker arm assem-
blies.
Installation
(1) Inspect all surfaces with a straightedge if there
is any reason to suspect leakage.
(2) Coat the new gaskets with Mopar Sealer
Part
Number 1057794.
(3) Remove the cylinder heads from the holding
fixtures Tool C-3626 and install on the engine.
(4)
On
273 and 318 Cubic Inch Engines,
install and
tighten all head bolts starting at top center, to 85
foot-pounds using the torque sequence, as shown in
Figure 67. Repeat the procedure, retightening all head
bolts to 85 foot-pounds torque.
(5) On
361,383 and 426 Cubic Inch Engines;
torque
all head bolts to 70 foot-pounds torque in sequence,
as
shown in Figure 68. Repeat the procedure retighten
