Product Information
The Patriot Tight Tuck Headers are designed for the 429-460 Ford 385 motors in street rods manufactured between 1908 and 1967. The header set includes a right side header, a left side header, two header gaskets, sixteen 3/8 header bolts, six 3/8-16 hex nuts, two reducers, six 3/8-16 x 1 collector bolts, and two collector gaskets. The headers are made to fit snugly and provide optimum clearance.
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 actor orque soecs starong in
the center and workine outward
Before starting, allow the vehicle to cool, disconnect the battery, and spray
a penetrating oil on all hardware and hittings 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
DISASSEMBLY
- If the car does not currently have an exhaust system installed, skip down to the Installation section
- Apply penetrating oil to all nuts and bolts to be removed.
- Disconnect the head pipes from the exhaust manifolds and remove the manifolds. Depending on the application, you may need 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.
- Remove the gaskets and any gasket material or any carbon deposits that remain on the head surface. The use of a gasket removal agent or scraper will ease the removal of any gasket material. Use care not to get debris into ports or spark plug holes.
INSTALLATION
- Some Patriot Tight Tuck Headers are the same for left and right sides; others are specific to each side. Determine which type you have.
- Carefully check the fit of each header for clearance. Pay special attention to motor mounts and any lines or hoses that might come in contact with the headers. It is not uncommon to have to trim motor mounts or move lines and hoses to clear the headers. Additionally, steering shafts and link ages should be clear of any interference and suitably modified if necessary. In some cases, a Mini Starter might be necessary as well.
- When you are satisfied with the fit of your header, slip into place using the supplied gasket and special header bolts. Use anti seize on headers bolts if installing on Aluminum Heads.
- Tighten the header bolts evenly starting in the center and working your way out.
- Install the reducers using the supplied gaskets and hardware.
- Weld the reducers to the exhaust system and install them onto the headers utilizing the gaskets and bolts supplied. Your exhaust can be fabricated now from the reducers back. Go to www.patriotexhaust.com for a complete line of mufflers, tips and tubing to complete your exhaust.
- Install 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.
- Check to make sure that all the wiring, brake lines, hoses, etc. are clear of the headers or any exhaust component.
- Connect the battery cables.
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
