PerTronix JBA Exhaust 1830S-6 - Manual (Page 2)

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 af-
fect 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 re-
turned 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.
See Note below for tool usage.
Tools: Power Steering Pump Pulley Puller. Snap-On ® part number CJ117A or equivalent.
Power Steering Pump Pulley Installer. Snap-On ® part number CJ113B101 or equivalent.
Note: A less expensive alternative: Lisle builds a puller (Pt #40000). It can be found in most auto parts stores.
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 disconnect the Y-pipe from the exhaust manifold.
4. Begin with the driver .s side. Remove the spark plugs and plug wires. Then unbolt and remove the exhaust manifold.
Using a scraper, remove all carbon deposits and high spots from head surface. If your vehicles power steering bracket
interferes with the removal of the factory manifold, see the special section below.
NOTE: Some vehicles equipped with power steering may require the removal of the power steering pump and bracket.
Not all vehicles will require the removal of this hardware.
5. Using a scraper, remove all carbon deposits and high spots from head surface.
6. Install the headers using the supplied gaskets and hardware. Tighten to factory specifications.
