HEADERS: These components are designed to improve the exhaust efficiency of the GM C.P.I. (Central Port Injection) V8 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.
Suggested Tools Needed for Installation. This vehicle has metric fasteners:
❑ 3/8" ratchet socket set with extensions and universal 13mm and 15mm swivel sockets
❑ Set of combination wrenches
❑ Jackstands, screwdrivers, pliers, crescent wrench, etc.
❑ Liquid penetrant, (GM #1052627) anti-seize compound (GM #5613695)
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.
NOTE: High temperature spark plug wires and boots are recommended to withstand heat from Headers.
