rail. Reinstall the bump stop bracket
while bolting the brake line heat shield
supplied in the PowerPack kit under the
nuts securing the bracket to the frame
rail (see Figure 3). Install a

locknut through the heat shield and into a
corresponding hole on the engine mount
bracket.
12. Inspect the cylinder head exhaust
flange surfaces. Remove any loose carbon,
rust, old gasket material, etc. as required
to provide a clean, flat manifold mounting
surface.
NOTE: The Banks PowerPack
®
exhaust
manifolds feature a heavy duty machined
flange that is designed to bolt directly
against the cylinder head without the
necessity of gaskets, which are prone to
deteriorate and blow out in time. In some
instances the factory cylinder head flange
surfaces may have become excessively
eroded from leaking factory exhaust
manifolds such that the Banks manifolds
will not seal to the head. In these instances
gaskets will have to be installed between
the head and manifold to provide a seal.
13. Bolt the Banks exhaust manifolds
to the cylinder heads while noting the
following items:
NOTE: It may be necessary to turn front
wheels all the way to the left to provide
installation clearance.
A. Three different bolt lengths are
utilized. Refer to Figures 4 and 5 for bolt
locations.
NOTE: Due to the heat soaking
characteristics of cast manifolds, spark
plug heat shields are required in the factory
application. Banks TorqueTubes, however,
do not retain heat in the tubes. Therefore,
the spark plug heatshields are unnecessary,
and in some cases may cause engine
misfire due to deterioration of the shield
insulation. We recommend that the factory
heat shields not be reinstalled with the
