PLEASE READ BEFORE PROCEEDING

PerTronix thanks you for choosing a Patriot Exhaust Product. To realize the potential of Patriot’s engineering and excellent fit, Please Read and Understand these instructions completely prior to starting the installation.
Check that you received all the parts listed on the parts list, if you have any concerns, please contact PerTronix before continuing . Headers will have the part number stamped in the flange.
Work Smart – Work Safe! Most Header and Exhaust Installation are best performed on a lift. If a lift is not available, raise the vehicle and support on quality Jack Stands on level ground. Do not rely on a jack!
Many factors affect he installation of exhaust headers, including worn or aftermarket motor mounts, previous accident damage, aftermarket cylinder heads that may have relocated port or spark plug locations, suspension and steering changes, sagging of original unibody structures due to age.
Coating Notes: Coatings can be marred during installation if you are not careful. If you are breaking in a new motor, the extreme heat can alter the appearance of the coating and this is not a warranty issue. We recommend breaking in new motors with stock manifolds or an old set of headers.
We use sealing beads on all our headers. The raised bead creates a better seal virtually eliminating leaks if installed properly. It is important to install all header bolts lightly snug and then tighten to factory torque specs starting in the center and working outward.
Before starting, allow the vehicle to cool, disconnect the battery, and spray a penetrating oil on all hardware and fittings that will need to be removed. Once you remove your manifold, clean the sealing surface on the head of any old gasket debris or carbon build up.

These headers will not fit a Saginaw 800 series close-ratio power steering box without modification due to the increased size of this power steering unit.
Will NOT fit 67-69 Camaro with original Air Conditioning.
70-78 with A/C need part # H7608 A/C bracket, 79 and later with short compressor use stock bracket

DISASSEMBLY

1. Remove and mark all spark plug wires and then remove all spark plugs.
2. Disconnect the head pipes from the exhaust manifolds and remove the manifolds. Depending on the application, you may be required to remove the alternator, dipstick, clutch linkage, and/ or oil filter. In some cases, it may be necessary to remove the starter and power steering unit. Only remove what is necessary to allow the removal of the manifolds or the installation of the headers.
3. Remove any gasket material or any carbon deposits that remain on the head surface.
4. At this point it may be necessary to cut the head pipes to allow room to install the headers. If you are installing a new exhaust system you may cut the head pipes any where you choose, but if you are using the existing exhaust you need to cut the head

ASSEMBLY

1. Install the headers (Driver side from the bottom of the vehicle, passenger side from above). Slide the headers into place and install a bolt at either end of the header to hold them in place.
   This will allow you to determine proper fit.

2. Once you have determined proper fitment, install the gaskets. Install all of the header bolts supplied and hand tighten. Tighten all the bolts evenly from the center out.

3. Install any accessories that were removed during the header installation.
   NOTE : Some accessories require different brackets than stock and some require the addition of spacers between the bracket and header flange. An example would be on some Chevy applications the driver’s side front bolt must use the original (factory) bolt and use the supplied spacer between the flange and the accessory bracket.

4. Install the reducers and determine the connection to the exhaust system.

5. Weld the reducers to the exhaust system and install them onto the headers utilizing the gaskets and bolts supplied.

6. Install the spark plugs and connect the wires to the proper plug. If the spark plugs have a lot of miles on them, now would be a good time to replace them with PerTronix Flame Thrower Wires. When you install the spark plugs, apply a small amount of anti-seize to the threads.

7. Check to make sure that all the wiring, brake lines, hoses, etc. are clear of the headers or any exhaust component.

8. Re-connect the battery cable.

IMPORTANT CHECK LIST

• Be sure that all brake lines, transmission lines, and fuel lines are clear of headers and/or connector pipes.
• All spark plug wires, battery cables, or other electrical components should be clear of headers and/or connector pipes.
• If dipstick tube was removed , make sure it is installed properly and that the dipstick has been replaced.
• Double-check the tightness of all bolts including brackets and accessories.

START THE ENGINE

Start the engine and allow it to warm up to operating temperature. Check for any unusual noises or exhaust leaks. If everything is OK, stop the engine and tighten all bolts while the engine is still warm.
NOTE : Check the bolts periodically to make sure they have not loosened. Re-tighten after the first 500 miles and then again at 1000 miles
