Installation Instructions

and Warranty Information

Ford Small Block Street Rod Headers

Part # 1615S

Read all instructions carefully before attempting installation.

Rev.2 04-11 DSL

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.
