PLEASE READ BEFORE PROCEEDING
PerTronixo thanks you for choosing a Patriot Exhaust Product. To realize the
potential of Patriot’s engineering and excellent fit, Please Read and
Understand these instructions completely prior to starting the installation.

any concerns, please contact PerTronix before continuing. Headers will have
the part number stamped in the flange. Work Smart — Work Safe! Most Header and
Exhaust Installation are best performed on a lift. If a lift is not available,
raise the vehicle and support on quality Jack Stands on level ground. Do not
rely on a jack! Many factors affect he installation of exhaust headers.
including worn or aftermarket motor mounts, previous accident damage,
aftermarkel cylinder heads that may have relocated port or spark plug
locations, suspension and steering changes, sagging of original unibody
structures due to age.
Coating Notes: Coatings can be marred during installation if you are not
careful. If you are breaking in a new motor, the extreme heat can alter the
appearance of the coating and this is not a warranty issue. We recommend
breaking in new motors with stock manifolds or an old set of headers. We use
sealing beads on all our headers. The raised bead creates a better seal
virtually eliminating leaks if installed properly. It is important to install
all header bolts lightly snug and then tighten to factory torque specs
starting in the center and working outward. Before starting, allow the vehicle
to cool, disconnect the battery, and spray a penetrating oil on all hardware
and fittings that will need to be removed. Once you remove your manifold,
clean the sealing surface on the head of any old gasket debris or carbon build
up.
To be used with the following GM Crate Engines, part #1927456, 19257460,
