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. 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. Disconnect the negative battery cable from the battery
3. Apply penetrating oil on all accessible fasteners and fittings before attempting to remove
them.
4. From underneath the vehicle, loosen the bolts connecting the exhaust system to the exhaust
manifolds. Move the exhaust system back about 1/2” to gain workspace.
5. If Equipped, remove the EGR connection from the stock exhaust manifold. Depending on
model, this could be on either the Driver or Passenger side.
6. Remove Oil Dipstick Tube, it is bolted to the cylinder head on the driver’s side. Take care not
to damage O Ring at the bottom of the tube.
7. Unbolt the bracket and cable from the passenger side, above the exhaust manifold. Retain the
larger bolt for reuse.
8. Unbolt both the Driver’s and Passenger’s side exhaust manifold and remove. Remove the
gaskets and any gasket material or carbon deposits that remain on the head surface. The use of
a gasket removal agent will ease the removal of any gasket material. Use care not to get debris
into the exhaust ports.
9. The Oil Dipstick needs to slide through the header and into the block as you install the Drivers Side header. On models with the EGR on the drivers side, loosely thread the EGR tube into
the header before bolting the header to the head. Apply a small amount of anti seize to the sup-
plied Header Bolts and start all the headers bolts with lock washers. Torque the bolts to 23 ft.
lbs. Starting from the center and working out.
10. Tighten the EGR Tube if applicable and tighten the Oil Dipstick bolt.
11. Slip the Passenger side header into position from inside the wheel well. On models with
the EGR on the Passenger side, loosely thread the EGR tube into the header before bolting the
header to the head. Apply a small amount of anti seize to the supplied Header Bolts and start all
the headers bolts with lock washers. Torque the bolts to 23 ft. lbs. Starting from the center and
working out.
12. Tighten the EGR Tube if applicable.
12. Re-attach the cable and bracket on top of the header using the (1) original bolt and the (2)
additional bolts supplied with this kit.
13. Apply a thin coasting of high Temp, Sensor Safe Silicone Sealant to the collector domes and
re-connect the exhaust system to the new headers using the hardware provided.
14. Check that all bolts are tight. Make sure that all wiring, fuel lines, transmissions lines, brake
lines etc are clear of the headers and the exhaust and relocate as necessary.
15. Reconnect the negative battery cable.
7. Start the engine, check for leaks and test drive. Then let engine cool and then re-torque the
header bolts.
18. Periodically check and retighten the header bolts.
