3. Apply penetrating oil to all nuts and bolts to be removed.
4. Remove and mark all spark plug wires and then remove all spark plugs.
NOTE: Grasp spark plug boot, not the wire, and use a twisting motion while pulling the wire
from the plug.
5. Disconnect the exhaust pipes from the exhaust manifolds and remove the manifolds. Remove
the Dipstick, Oil Filter, Oil Pressure Sending unit, Clutch Linkage, and Air Conditioning
compressor. These headers will not work with A/C.
6. Remove the Bell crank and lower rod from the transmission to key locking device.
7. Remove any gasket material or any carbon deposits that remain on the head surface. The use
of a gasket removal agent will ease the removal of any gasket material. Be careful to not get
any debris in the spark plug holes or exhaust ports
8. At this point it may be necessary to cut or remove the exhaust pipes to allow room to install the
headers. If you plan to reuse your existing exhaust, it is recommended that you remove the
exhaust and then cut it to fit after the headers are installed.
INSTALLATION
LEFT SIDE
1. Starting from below, work the header up through the chassis and into position.
2. Start a bolt on each end of the header to hold in place. Do not tighten at this time.
3. With the header still loose, work the clutch linkage back into position.
4. Reinstall and fully tighten all linkages, the oil pressure sender, and the oil filter.
5. Slip the gasket into place and install all of the header bolts and lock washers supplied and
hand tighten. Tighten all the bolts evenly to a torque of approximately 35 Foot Pounds on iron
heads, working from the center outward.
RIGHT SIDE
1. Place a jack with a board between the jack and the oil pan to support the motor. Loosen the
transmission mount bolts or nuts. Remove the left side motor mount and jack the motor up 2”
minimum. Starting from below, work the header up through the chassis and into position. Start
a bolt on each end of the header to hold in place. Do not tighten at this time.
2. Lower the engine back into position and replace the motor mount.
3. Replace the Starter Motor.
4. Slip the gasket in place and install all of the header bolts and lock washers supplied and hand
tighten. Tighten all the bolts evenly to a torque of approximately 35 Foot Pounds on iron
heads, working from the center outwards.
5. On automatic transmission cars, check that the transmission cooler lines do not contact the
header tubes. Re route as necessary.
6. Install the reducers and determine the connection to the exhaust system.
7. Weld the reducers to the exhaust system and install them onto the headers utilizing the
gaskets and bolts supplied.
8. Install the spark plugs and wires.
9. Re install the dipstick and check the oil level since you removed the filter.
10. Check to make sure that all the wiring, fuel lines, transmission cooler lines, brake lines, hoses,
etc. are clear of the headers or any exhaust components and reroute or relocate those
components as necessary.
11. Connect the battery cable.
