Assembly
1. Place the supplied port gasket over the studs (if
equipped) on the cylinder head. Install the Edelbrock
Header on the studs (if equipped) using the provided
8mm bolts, and lock washers on all bolts. Use
supplied lock nuts and hardened washers on the
studs (if equipped). Tighten all flange bolts and nuts
at this time.
2. Re-install the catalytic converter to the hangers.
Using the supplied 5/16 bolts, nuts, lock washers,
and hardened flat washers and gaskets, attach the
catalytic converter to the header collector flange.
Note: (The lower bolt of the collector is used to
secure the supplied heat shield). Using supplied
10mm bolt and washer, attach the heatshield to the
block just above the oil pan rail.
3. Check all hydraulic, vacuum, water, and fuel lines to
ensure there is adequate clearance from the header.
Using anti-seize on threads, install O2 sensor and re-
connect plug.
4. Re-connect the battery.
5. At this point, it is a good idea to check everything
over to make sure nothing was missed during
assembly.
6. Start vehicle and bring vehicle up to operating
temperature. Check for leaks of any kind.
7. Turn off engine and let cool. Tighten all the bolts
again.
Disassembly
1. Raise and support the vehicle on a flat stable surface
using the floorjack and proper load rated jackstands.
2. Disconnect the battery.
3. Remove nut and bolts retaining heatshield and remove
heatshields.
4. Remove four nuts that retain catalytic converter to the
stock manifold.
5. Unplug and unclip oxygen sensor wire located above
the catalytic converter.
6. Remove the clamp retaining the catalytic converter
pipe to the intermediate pipe and unhook the catalytic
pipe brackets from the hangers. Remove catalytic
converter.
7. Unbolt and remove the stock manifold and gasket.
