WARNING: These headers are legal for Off Highway use (except in California or states that have adopted Cali­fornia emission standards) or Racing use (which may never be used on a Highway), or for use on pre emission

controlled motor vehicles/motor vehicle engines (pre 1974 domestic vehicles certied to California standards, pre

1974 domestic vehicles certied to Federal standards and all pre 1974 Foreign vehicles) Only.

Read all instructions carefully before attempting installation.

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 num-

ber 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 affect the installation of headers, some of which are broken or aftermarket

motor mounts, accidents that impact the conguration 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 ange to be raised off the

cylinder head the thickness of the sealing bead. It is important when installing the header, to in-

stall 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. Sec-

ond, 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.
