the header gaskets and stick the gaskets to the header flanges. Masking tape can be
used to help hold the gasket to the header.

utilizing the star washers with the header bolts. Do not tighten the bolts at this time.
4. Apply a liberal film of Ultra Copper Hi-Temp Sensor-Safe Silicone Sealer to the slip joint
of the L1 tube.
5. From above, install the L1 slip tube around the steering shaft and into the main body of
the header.
6. Install the passenger side header with gasket attached using the star washers and
header bolts supplied, but do not tighten at this time. (It may be necessary to raise the
engine a couple of inches to install the header on this side).
7. Reinstall the starter.
8. If applicable, reinstall the O
2
sensors using a very small amount of Ultra Copper Hi-
Temp Sensor-Safe Silicone Sealer on the threads.
