8. Replace the spark plugs finger tight so debris will not get into the cylinders while
cleaning the head surface. We recommend the use of a gasket scraper, wire brush,
and sanding block to adequately clean the surface.
9. After cleaning is complete remove the spark plugs again.
10. Modify the A/C bracket as shown in Figure 1, Page 3.
ASSEMBLY
1. Apply a THIN film of Ultra Copper Hi-Temp Sensor-Safe Silicone Sealer to each side of
the header gaskets and stick the gaskets to the header flanges. Masking tape can be
used to help hold the gasket to the header.
2. Remove right side motor mount bolt and jack motor up approximately 1-
1/2” to 3”.
CAUTION: Be sure to place a board between the oil pan and the jack.
3. Starting from above, work header down into position but do not install any bolts yet.
4. Lower the motor and check for header clearance. Replace motor mount bolt. (On some
later models the heater line will need to be repositioned to gain clearance).
5. Using the supplied header bolts and lock-washers, apply a small amount of anti-seize
to the bolts and start the most restrictive bolts first. Tighten to a final torque of 35 ft. lbs.
6. Reinstall dipstick tube.
7. Install valve from stock air injection tree onto header air injection tree.
8. Install the spark plugs and attach the appropriate wire to the spark plug and reattach
the spark plug wire looms. It may be necessary to reroute wires to clear the headers.
9. Install diverter valve on air injection pump and all hoses.
10. Starting from above, work header down into position.
11. Using the supplied header bolts and lock-washers, apply a small amount of anti-seize
to the bolts and start the most restrictive bolts first. Tighten to a final torque of 35 ft. lbs.
12. Install the modified air conditioning bracket using stock stub and tubular spacers
provided.
13. Install the spark plugs and attach the appropriate wire to the spark plug and reattach
the spark plug wire looms. It may be necessary to reroute wires to clear the headers.

15. Install O
2
sensor in left header.
16. Bolt Y Pipe assembly to the headers.

START THE ENGINE
Start the engine and allow it to warm up to operating temperature. Check for any unusual
noises or exhaust leaks. If every thing 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
IMPORTANT CHECK LIST
Be sure that all brake lines and fuel lines are clear of headers and/or connector
pipes.
