Hedman Hedders - This is our standard line of hedder for passenger cars and trucks. Many are 50 State legal while others are for use in vehicles which may not be used on highways. Hedman Hedders come standard with a black coating.

127. Late model chassis. Engine offset to passenger side of vehicle. 208. Due to clyinder heads (aluminum) generation 6 engines, 502 BB Chevy will have clearance problems on some applications. Bottom of hedder flanges may hit head bolts. Notching may be necessary. 213. Elite replacement gasket #27550. 225. Designed for use with a Trans-Dapt throttle body spacer. 45. Not legal for sale or use in California on pollution controlled motor vehicles. 5. With A.I.R. system. 6. Modification to stock exhaust required to retain catalytic converter. B. Not applicable or intended for street or highway use. Legal only for racing vehicles which may never be used upon a highway, check footnotes also. D. Not legal for sale or use in California.


Hedman`s Standard-duty, Uncoated Headers are manufactured using 18 gauge, mandrel bent primary tubes (some models built using thicker 16 or 14 gauge tubing), and 1/4 flanges (some models use 3/8" flanges).

The factory black paint applied to uncoated headers is not hi-temp, and is for pre-installation protection only. For the ultimate in protection against the elements, we suggest Hedman`s Original HTC coating.
