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. Spray WD-40 or some type of penetrating oil on all accessible fasteners and fittings before attempting to remove them.
3. From underneath the vehicle, remove nuts attaching the manifolds to the exhaust pipe.
4. Remove bolt attaching steering shaft to steering rack. Slip shaft off of rack.
5. From above, remove oil ll cap. Remove engine cover by tugging upwards gently on the lower
corners. Remove the bolt attaching the oil dipstick to head. The dipstick will swing out of the way. (On
6812S & 6813S remove dipstick)
6. Carefully remove spark plug wires. Twist boot prior to tugging on them. Do not pull directly on the
wire. Remove spark plugs.
7. Remove bolts attaching manifolds to head. Remove manifolds.
8. Unbolt Catalytic Converter assemblies from the exhaust pipes. Unplug and remove oxygen sensors.
9. Clean gasket surface, be careful not to gouge the head.
10. On the G8 attach the included O2 extender to driver’s side wire harness. Two O2 extender’s on
Camaro applications.
11. Install headers using gaskets and supplied hardware.
12. Re-install spark plugs, 02 Sensors, and plug wires. Re-attach/install dip stick.
13. Check to ensure there is adequate clearance on all fuel lines, brake lines, battery cables, wire harnesses, etc.
14. Re-check everything!
15. The G8 headers are intended to work with the supplied Stacker Flanges/Starter Tubes.
The Camaro can be installed using the supplied Stacker Flanges/Starter Tubes or one of our hight ow
mid pipes; 6812SD, 6812SDC, 6813SD or 6813SDC.
16. Start engine, check for leaks and test drive. Then let engine cool and re-torque header bolts.
17. Periodically check and retighten header bolts.
