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.

Notes on Specific Applications: These shorty headers are designed to be a direct replacement for OEM cast iron

manifolds, known as high flow manifolds used on many AMC cars and Jeep vehicles. Some of the vehicles listed above

came with different exhaust manifolds on one side and will require modification to exhaust down pipe on one side (see

below).

Jeep Application Note: When installing this system on some 1981-1991 Jeep Grand Wagoneer, 1981-1983

Cherokee, or 1981-1988 J series pick-up, check the location of the outlet of the left side exhaust manifold. If the outlet

is located under the 3rd spark plug, no modification will be needed. If the outlet is directly under the 4th spark plug,

the stock down pipe will require modification.

AMC Car Application Note: When installing this system on 1970-1979 AMC cars with (Type 1) right side manifold,

no modification is needed. If your car has (Type 2) right side manifold, modification to stock down pipe is required.
