5. Using a scraper, remove all carbon deposits and high spots from head surface. At this time apply a high temperature sealer to ex-
haust pipe flare in order to avoid problems due to lack of space later on in the installation.
6. Slide the new gasket (supplied) over the center studs. You may need to start nuts and washers on center bolts before pressing header
to the head.
7. Install the header using supplied hardware.
8. For 1992 –1995 models only begin on the passenger side by removing the bolts attaching the EGR tube to the exhaust manifold.
Once the bolts have been removed, slightly loosen the tube at the EGR valve (located on the back of the intake manifold) Do not
Remove Tube.

two nuts and washers for re-installation).
10. Using a scraper remove all carbon deposits and high spots from head surface. At this time apply a high temperature sealer to ex-
haust pipe flare, in order to avoid problems due to lack of space later on in the installation.
11. Slide the new gasket (supplied) over the center studs. You may need to start the nuts and washers on center bolts before pressing
header to the head.
12. Once again, install the passenger side header using the supplied hardware..
13. Then apply some silicone to the base fitting of the EGR tube and re-tighten the air tube using the hardware provided.
Note: Due to the design and materials used on the factory Y-pipe, it is common to have the Y-pipe assembly distort from its original
shape due to repeated heating and cooling. The heating and cooling of the assembly works as a stress relieving
14. Reconnect the exhaust system to the header using the hardware provided (Note: some 1992-1995 models may require a flare
reduction donut for exhaust pipe).
15. Check to make sure there is adequate clearance on plug wires, battery cables, wire looms, brake lines, etc.
16. Re-connect battery cables.
