Inspect the exhaust mounting
surfaces of the cylinder heads and
remove any rust or carbon, which
would prevent the TorqueTube
manifolds from sealing. Zip-tie cables
away from left-side Torque Tube as
shown in Figure 4.
Note: Do not use the factory exhaust
manifold gaskets upon reinstallation.
Banks TorqueTubes have a machined
surface and are designed to seal
without gaskets.

On the left engine block, remove
the factory knock sensor heatshield
located just below the exhaust ports
next to the oil filter. Install the Banks
knock sensor heatshield to the factory
using the factory hardware (see Figure
5).

Apply a small amount of antiseize
on the threads of the supplied 8
mm manifold bolts. Lift the right
side TorqueTube manifold into place
and install one 8 mm bolt at the
front and rear of the TorqueTube to
hold in place. Install the remaining
8 mm manifold bolts to secure the
TorqueTube. Repeat this step for the
left side TorqueTube. Reinstall the
dipstick tube and o-ring. Reattach the
bracket to the engine block as shown
in Figure 2.

Re-secure the bracket to the
alternator support using the bolt
previously removed. Re-install the spark
plug wires in their original locations.
Torque all manifold bolts to 26 ft-lbs.
