Position.
2. Apply grease to the contact surfaces of the rocker
arms and rocker arm pivots. Install the rocker
arms and rocker arm pivots on one cylinder head,
and start the two hex flange screws.
3. Torque the hex flange screws to 11.3 N·m
(100 in. lb.). See Figure 11-42.

Nuts (Stud Design).
Install Push Rods and Rocker Arms
NOTE: Push rods should always be installed in the
same position as before disassembly.
1. Note the mark or tag identifying the push rod as
either intake or exhaust and cylinder #1 or #2. Dip
the ends of the push rods in engine oil and install,
making sure that each push rod ball seats in its
hydraulic lifter socket. See Figure 11-41.
b. Thread the opposite end of the stud, with the
preapplied locking compound, into the
crankcase, until the specified height from the
crankcase surface is achieved. See Figure
11-39. When threading in the studs, use a
steady tightening motion without interruption
until the proper height is obtained. Otherwise
the frictional heat from the engaging threads
may cause the locking compound to set up
prematurely.
The studs closest to the lifters must have an exposed
height of 75 mm (2 15/16 in.).
The studs furthest from the lifters must have an
exposed height of 68 mm (2 3/4 in.).
c. Remove the nuts and repeat the procedure as
required.

Specified Height.
4. Check that the dowel pins are in place and install
a new cylinder head gasket (printing up).
5. Install the cylinder head. Match the numbers on
the cylinder heads and the crankcase. See Figure
11-32. Make sure the head is flat on the gasket
and dowel pins.
6. Lightly lubricate the exposed (upper) threads of
the studs with engine oil. Install a flat washer and
hex nut onto each of the mounting studs. Torque
the hex nuts in two stages; first to 16.9 N·m
(150 in. lb.), then finally to 33.9 N·m (300 in. lb.),
following the sequence in Figure 11-38.
