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 finished. 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 flanges. 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. Remove the decorative cover on top of the engine. The cover is attached by rubber grommets
that slide onto plastic studs. Carefully, but firmly pull the cover off the studs.
3. Spray WD-40 or some type of penetrating oil on all accessible fasteners and fittings before
attempting to remove them.
4. From underneath the vehicle disconnect the exhaust system from the catalytic converter
assembly. This may require heating the slip connection if your pipe has an indentation from
the U-bolt clamp.
5. Next unbolt the catalytic converter assembly from the manifold.
6. On vehicles equipped with a plastic power steering fluid reservoir it will be necessary to
move it out of the way. From above, remove the power steering reservoir from its’ bracket by
releasing the spring tab on the bracket and sliding the reservoir up and out of the way. DO
NOT DISCONNECT THE HOSE, just swing it out of the way.
7. Unbolt the heat shield from the top and bottom and unbolt the bracket that attaches to the
block. Caution: Heatshield edges are sharp. Carefully remove the heatshield pieces from the
bottom.
8. Unbolt the manifold from the head. It will need to be removed from the bottom (seriously). Try
laying it flat, top up with the ports toward the right side and slide it over the steering rack. Be
patient and wiggle it gently until it is out.
9. Using a gasket scraper, remove all carbon deposits and high spots from head surface. At this
time apply a high temperature sealer to exhaust pipe flare in order to avoid problems due to
lack of space later on in the installation.
10. Using the original factory gaskets and JBA fasteners install the new headers. Be sure to tighten nuts
and bolts to factory specifications.
11. Reconnect the the catalytic converter assembly to the headers using the original gasket and hardware.
12. Reconnect the exhaust system to the catalytic converter assembly.
13. Replace the power steering reservoir.
14. Check to make sure there is adequate clearance on plug wires , battery cables, wire looms,
brake lines, etc.
15. Re-connect battery cables.
16. Recheck everything!
17. 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.
18. Replace the decorative cover on top of the engine.
19. All tubular headers require maintenance including periodically checking and retightening of the
header bolts.
