PerTronix© thanks you for choosing JBA HEADERS, the best tting, highest quality header on the market. In order to realize the full potential of our good t, 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 ange. 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 aect the installation of headers, some of which are broken or aftermarket motor mounts,
accidents that impact the conguration of the frame, and/or the installation of dierent 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 eectively prevents leaking gaskets. It is normal for the ange to be raised o 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 at installation
of the ange. The torque sequence from one ange to another will vary, but generally every bolt on a header
should be rst t snug, starting from the inside of the ange working out, alternating from top to bottom so
that the bolt connects the ange 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 oor is solid and at, with adequate lighting. Do not attempt to work
on a hot engine. Heat causes metal to expand and makes removal of fasteners dicult 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 o the jack stands.
2. Disconnect the Negative Battery Cable from the battery.
3. Apply penetrating oil on all accessible fasteners and ttings before attempting to remove them.
4. Unplug the Oxygen Sensors from the exhaust system. Disconnect the exhaust system from the catalytic
converter assembly. Remove the converter assembly from the vehicle.
5. Remove the Starter Motor.
6. Remove the motor mount nut under the passenger side manifold.
