Read all instructions carefully before attempting installation.

PerTronix© thanks you for choosing JBA HEADERS, the best fitting, highest quality header on the market. In order to realize the full potential of our good fit, please read and understand these instructions
completely prior to starting work.
Check to make sure you received the proper parts for your application. The header number will be
stamped on the engine flange. If you are unsure you have received the proper parts call before you start
work.
Be sure to work safe! Whenever you work under the vehicle be sure that it is located on level, solid
ground and is supported by adequate safety stands! Remember: Hot asphalt will not support most jack
stands!
Many factors affect the installation of headers, some of which are broken or aftermarket motor mounts,
accidents that impact the configuration of the frame, and/or the installation of different engines or aftermarket cylinder heads.
Attention Customers breaking in new engines: Due to the extreme heat generated during the break-in
process, the appearance of the ceramic coating may be altered in certain areas. The protection characteristics and thermal barrier properties of the coating is never compromised. It is recommended that a cast
iron manifold or old set of headers be used for this process.
Notice: The coating of these headers can be marred or scratched during installation. If the header needs
to be returned and is damaged, you will be charged for recoat.
JBA uses sealing beads on all its headers. We have found that when installed correctly, the raised bead around
each port increases the pressure exerted on the gasket directly adjacent to the port and effectively prevents leaking gaskets. It is normal for the flange to be raised off the cylinder head the thickness of the sealing bead. It is
important when installing the header, to install all bolts loosely, then tighten evenly to ensure the flat installation
of the flange. The torque sequence from one flange to another will vary, but generally every bolt on a header
should be first fit snug, starting from the inside of the flange working out, alternating from top to bottom so
that the bolt connects the flange to the manifold to the point where they barely touch. Second, using the same
inside-out pattern, tighten each bolt until nished. This method will help prevent leakage and will give the user
the best possible performance out of their pair of headers.
1. Place vehicle in a location where the floor is solid and flat, with adequate lighting. Do not attempt to work
on a hot engine. Heat causes metal to expand and makes removal of fasteners difficult at best. Disconnect the
battery cables from the battery. Raise the front of the vehicle to obtain adequate access to the bottom exhaust
manifold anges. Use large-base jack stands to support the vehicle. Do not rely on the jack! Block the tires to
prevent the vehicle from rolling off the jack stands.
2. Spray WD-40 or some type of penetrating oil on all accessible fasteners and ttings before attempting to
remove them.
3. From underneath the vehicle disconnect the exhaust system from the exhaust manifolds by unbolting the (3)
bolts at the collectors. Then unbolt the driver side catalytic converter from the exhaust assembly and temporarily remove it from the vehicle.
PASSENGER SIDE
4. On the passenger side remove the (4) bolts attaching the heat shields to the factory manifold.
5. Next, carefully unplug the O2 sensor from its harness.
6. Now remove the nuts attaching the factory manifold to the cylinder head. With the manifold out of the way
remove the mounting studs from the cylinder head.
7. Using a small wire brush or similar instrument, clean any carbon deposits left on the head surface. Be careful
not to gouge the aluminum head.
8. Transfer the O 2 sensor from the factory manifold to the new passenger side header. Apply a small amount of
anti seize to the threads for the sensor before installing it in the new header. Use caution not to drop or damage
the sensor, they are fragile.
9. Now you are going to install the new JBA Header, but first there is some preparation of the hardware required. Apply anti seize to the threads of the new fasteners. Install the new JBA Header using the supplied
gasket and fasteners. Torque to 23 ft./lbs.
DRIVER’S SIDE
10. Just like you did in step (4) remove the (4) bolts attaching the heat shields to the driver side factory mani-
fold.
11. Next, carefully unplug the O2 sensor from its harness. Unbolt the dipstick bracket from the head and remove
the dipstick tube.
12. Remove the nuts attaching the factory manifold to the cylinder head. With the manifold out of the way re-
move the mounting studs from the cylinder head.
13. Using a small wire brush or similar instrument, clean any carbon deposits left on the head surface. Be careful not to gouge the aluminum head.
14. Transfer the O 2 sensor from the factory manifold to the new driver side header. Apply a small amount of
anti seize to the threads for the sensor before installing it in the new header. Use caution not to drop or damage
the sensor, they are fragile.
15. As you did on the passenger side, prepare the hardware before installing the driver side header. Apply anti
seize to the threads of the new fasteners. Install the new JBA Header using the supplied gasket and fasteners.
Torque to 23 ft./lbs. Re-install the dipstick tube.
16. Install the driver side catalytic converter.
17. Connect the exhaust system to the new headers using hardware and gaskets supplied. Reconnect O2 sensors.
18. Check to insure adequate clearance between header and shifter cable (small cable that runs from rewall,
to brace on fender well, to transmission). More clearance can be gained by adjusting (bending) brace on fender
well.
19. Recheck everything!
20. Start the engine and let it warm up Check for leaks. Shut engine off and let it cool down. Check to make
sure all fasteners are tight.
21. All tubular headers require maintenance including periodically checking and retightening of the header
bolts.
