INSTALLATION INSTRUCTIONS
PLEASE study these instructions carefully before installing your new Shorty Header. If you have any questions, please call
our Technical Hotline at: 1-800-416-8628 from 7:00 am - 5:00 pm, Monday-Friday, Pacific Standard Time or e-mail

HEADERS: These components are designed to improve the exhaust efficiency of the Ford 5.0 Litre V8 engine with E.F.I.
(Electronic Fuel Injection). These tubular manifolds are a direct replacement for the factory exhaust manifolds. A
performance gain can be expected by the installation of this system. This system does not require welding for installation
and retains all O.E.M. emissions equipment.
SUGGESTED TOOLS FOR INSTALLATION:
❑ 3/8" ratchet socket set with extensions and sockets ❑ Jackstands, screwdrivers, pliers, crescent wrench, etc.
❑ Combination set of open-end wrenches ❑ Liquid penetrant, anti-seize compound
SPECIAL NOTICE: This Edelbrock part has received an Executive Order (E.O. #) from the California Air Resources Board
(C.A.R.B.) making it legal for street use on pollution-controlled motor vehicles in all 50 states. To assist you with emissions
equipment certification, we have included a silver fan shroud decal to help testing personnel verify that this part is a legal
replacement part on the vehicle for which it is cataloged. The adhesive-backed decal should be affixed to your fan shroud
next to the existing emission and engine specification decal. Do not cover your original equipment specification decal with
the Edelbrock fan shroud decal.
WARNING: The use of "Thermal Wrap" or any aftermarket coating process will void the warranty on your
headers. Those products can cause excessive heat and moisture buildup resulting in corrosion and early
failure of the system.
NOTE: High temperature spark plug wires and boots are recommended to withstand heat from Headers.
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.

5. Clean and inspect all sealing surfaces before
assembly.
• ASSEMBLY - LEFT SIDE
1. With manifold port gasket in place, start a
header bolt with lock and flat washer in the
rearmost bolt hole leaving enough room for the
manifold to slip into position.
2. Start balance of header bolts with lock washers
and tighten evenly.
• ASSEMBLY - RIGHT SIDE
1. With gasket in place, start all bolts except the
rear bolt with lock and flat washers on each.
2. Start rear bolt with A.I.R. tube support bracket in
place.
3. Tighten balance of header bolts evenly.
4. Re-attach exhaust pipes to TES manifolds using
your original nuts.
5. Connect all parts including battery.
