S&S SH-, P-, and KN- Series engines,

though they are similar, they are not the

manual. S&S pushrods are the same

in all these engines except for different

lengths for different engine styles and

displacements. Another important dif-

ference is whether a S&S Limiter kit is

installed in the lifters (tappets), which

changes how the pushrods are adjusted.

As stated in Part I, as well as the

oil pump install for this engine, when

After popping in one of the new wrist pin clips, posi-
tion the piston onto its rod orientated as per the S&S
instructions or your piston manufacturer. Then slip in
the wrist pin coated with fresh engine oil.

With new copper head gaskets (align the oil holes!) on

the cylinders, install the heads using the head bolts and

flat washers. Just thread the head bolts in until slightly

loose for now using a 12-point 7/16" box wrench.

With new gaskets (align the oil holes!) on the cases
and the ring compressor coated with oil, position
the compressor over the rings. Then gently move the
cylinder down over the piston making sure the rings go
smoothly into the cylinder’s bore.

Install the intake clamps using a 3/8" deep socket. Use

a flat-bladed screwdriver to keep the clamps centered

on the manifold. Then torque the head bolts to spec

in a star pattern using a 12-point 7/16" dog bone

extension.

With clean rags in the cylinder spigots so nothing falls
in, use a small flat-bladed screwdriver to work the
other wrist pin clip into its groove in the piston. Be sure
one of the clip’s ends is next to the groove’s gap.

With the intake manifold between the heads, move the

heads as needed so there’s no gap between the intake

ports and manifold. After you snug all the bolts in a

star pattern so the heads won’t move, roll the O-rings

into their slots.

Install the cylinder base nuts with a little oil on their
threads using a 7/16" dog bone extension. After you
snug all the nuts down, torque them to 20 ft-lbs. and
then 35-40 ft-lbs. in a crisscross pattern.

The S&S rocker assemblies, which are clearly marked

either FE-RI or FI-RE, go in next. Install them using

blue Loctite and a 1/4" Allen. Torque the S&S bolts to

15-18 ft-lbs. in a crisscross pattern.

With new O-rings and seals in the S&S pushrod tubes,

heads, and lifter blocks, slip the S&S pushrods (short

ones for the intake valves, long ones for the exhaust)

into their tubes and position them on the engine.
