Finish Notes: These headers ship with a temporary black paint applied at the factory to protect bare metal during storage and shipping. This coating is not a high-temperature finish and will burn off during initial use. For long-term protection, apply a high-temperature header coating or paint of your choice before installation.

Important: Designed for vehicles without A.I.R. (Air Injection Reactor) systems. Compatible with air conditioning, power steering, and both automatic and manual transmissions (floor shift only). Not legal for street use on 1975 and later model year vehicles—off-road and racing use only. Some modifications may be required for proper fitment on certain applications.

Backed by Hedman's limited lifetime warranty on construction and proudly made in the USA since 1954.
