HEADERS: These components are designed to improve the exhaust efficiency of the Ford Mustang GT engine. This system does
not

require welding for installation and retains all O.E.M. emissions equipment. These Edelbrock headers are street legal in all

50 states.

IMPORTANT NOTE:

Proper installation is the responsibility of the installer. Improper installation will void warranty and may result in

poor performance and engine or vehicle damage.

Suggested Tools Needed for Installation. This vehicle has metric fasteners:

❑ 3/8" and 1/4” ratchet socket set with extensions and universal 13mm and 15mm swivel sockets
❑ Set of combination wrenches
❑ Jack and jackstands, screwdrivers, pliers, crescent wrench, etc.
❑ Torque wrench
❑ Liquid penetrant, (GM #1052627) anti-seize compound (GM #5613695)
❑ Thread locking compount (Loctite)

SPECIAL NOTICE: This Edelbrock part has received an Executive Order number (E.O.#) from the California Air Resources Board
(C.A.R.B.) making it legal for street use in all 50 states. To assist you with emission equipment certification, we have included a silver
fan shroud decal to help testing personnel verify the this part is a legal replacement on the vehicle for which it is cataloged. The
adhesive-backed decal should be affixed next to the existing emission and engine specifications decal. Do not cover any part of your
original emission decal.

WARNING: The use of "Thermal Wrap" or any aftermarket coating process will void the warranty

on your Edelbrock Headers.

Those products will cause excessive heat and moisture buildup resulting in corrosion and failure of the header.

IMPORTANT NOTE:

Anytime you are raising an engine inside the vehicle, make sure the hood is open and that there is proper clearance

for wires, fuel lines, and hoses. Always properly secure the engine while it is raised, as the engine could cause

bodily harm if improperly raised and secured.

HEADER INSTALLATION

1. Remove the passenger side aluminum motor mount.

2. Remove exhaust manifold studs from cylinder heads.
Clean manifold gasket surfaces of all gasket material.

3. Using supplied gaskets, 8mm bolts, lockwashers, and
black hardened washers, install only bottom bolts,
and washers to hold gasket in place. Leave bolts
loose so header flange can be slipped over the
hardware. Use anti-seize compound on all bolts.

4. Working from under vehicle, slip the right

Edelbrock
shorty header up into place, taking care not to
damage gasket. Take your time and it will require
some maneuvering. Slide header down over the
manifold bolts.

5. From top of vehicle, install remaining right header
bolts, and washer on right header. Tighten header
bolts at this time, working from center bolts outward.

6. Reinstall the passenger side aluminum motor mount.

7. Remove the driver side aluminum motor mount.

8. Working from under vehicle, slip the left

Edelbrock
shorty header up into place. Install oxygen sensor
from original left manifold before slipping header over
manifold bolts.

9. Install remaining left header bolts and washers from
the top of the vehicle. Tighten header bolts working
from center bolt out.

10. Reinstall the driver side aluminum motor mount and
set the engine back down on the mounts, then
retighten the top-mount nuts.

Note: Adjust the engine from side to side for proper
header clearance.

11. Install starter.

12. Slip rack and pinion back into place while sliding
steering shaft back onto rack and pinion. Torque
rack and pinion bolts to 40 ft. lbs. Install steering
shaft bolt using thread locking compount on
threads.

13. Install headpipe assembly in reverse of removal.

14. Install D-nut gaskets supplied onto header outlet.

15. Bolt headpipe to Edelbrock shorty headers using
supplied 3/8 bolts, lockwasher, and flatwashers.
Use anti-seize compound on threads and tighten,
using care not to crush D-nut gaskets.

clamp connectors onto headpipe. Tighten clamps at
this time.

17. Re-connect all oxygen sensors.
