HEADERS: These components are designed to improve the exhaust efficiency of the GM C.P.I. (Central Port Injection) V8

headers are street legal in all 50 states.

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.
