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.

NOTE: Installation of this product requires an adequate workspace, general mechanic’s tools, general mechani­cal “know-how” and a reasonable degree of experience. Most auto enthusiasts with these resources will have
little difficulty installing these headers. However, you should carefully read these instructions before attempt­ing to install these headers. If in doubt, consult a professional mechanic. (Better to do it now than to get stuck
halfway through the installation.)

By installing your JBA Performance Exhaust product, you indicate that you have read this document and agree
with the following terms. The Purchaser is responsible for following all installation instructions and safety
guidelines supplied with JBA Performance Exhaust products.

PerTronix© assumes no responsibility for damages resulting from improper operation, misuse, abuse, or lack of
responsible care, or any problems resulting from incompatibility with other manufacturer’s products.

Included with your installation instructions is a copy of the product warranty. Please read it carefully before
you begin any work on your vehicle.

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.

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 important when installing the header, to install all bolts loosely, then tighten evenly to ensure
the flat installation of the flange. It is normal for the flange to be raised off the cylinder head the thickness of
the sealing bead.

To prevent leakage, it is important to tighten the flanges on any set of JBA headers carefully by using the proper
procedure. 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.
