Shorty Header
. If you have any questions, please

SHORTY HEADER: These components are designed as a system to improve the exhaust efficiency of the Ford 5.0 liter
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 the system. This system requires no welding
for installation and retains all O.E.M. emissions equipment.
Suggested Tools Needed for Installation: This vehicle has some metric fasteners.
❑ 3/8” ratchet socket set with extensions and sockets
❑ Combination set of open-end wrenches
❑ Jackstands, screwdrivers, pliers, crescent wrench, etc.
❑ Liquid penetrant, anti-seize compound
SPECIAL NOTICE: This Edelbrock Shorty Header 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
Shorty Header. Those products can cause excessive heat and moisture buildup resulting in corrosion and failure of the
system.
CAUTION: Due to higher underhood temperatures generated by shorty header, vehicles equipped with original spark plug
wires should have them replaced with high temperature plug wires for longer life.
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.

4. Remove EGR tube from right side.
5. Unbolt and remove both exhaust manifolds.
6. Clean and inspect all sealing surfaces before
