These HTC coated, standard-duty headers use TORK-STEP stepped tube technology to provide performance superior to any standard tube header design. Originally designed for racing applications, Hedman is the first manufacturer to mass produce this technology for the street.

All Hedman street Hedders are MADE IN THE USA, and are backed by a lifetime warranty against manufacturing defects! HTC coated stainless models also available.

UNLESS SPECIFICALLY STATED, ALL HEADERS ARE DESIGNED FOR USE WITH FACTORY PROFILE CYLINDER HEADS!
If your engine does not have factory cylinder heads, we strongly recommend you contact the aftermarket head manufacturer to confirm that the deck angle, exhaust port height and spark plug angle/position match the factory cylinder head design, before ordering your headers. If you are still unsure, please contact the Hedman Tech lines M-F 8am-4:30PM (Pacific) @ (562) 921-0404.

IMPORTANT!: Installing coated headers on an engine during the break-in period will cause discoloration. We recommend the use of factory manifolds, or an old set of headers, during the engine break-in period.

Tork-Step Hedders, manufactured exclusively
by Hedman Hedders, evacuate exhaust gasses from the combustion chambers faster than, and more efficiently than, stock manifolds or a standard tube hedder. The increase in available exhaust chamber volume allows for more fresh air/fuel mixture to be drawn in, creating a purer fuel charge packed with more power. The result is the tug you feel on the “seat of your pants” when you punch the accelerator...better known as TORQUE.

Once used only on race engines, Hedman Hedders was the first major manufacturer to incorporate this state of the art technology into hedders you can affordably install on your favorite musclecar.

This is a standard-duty hedder manufactured using 18 gauge tubes, 1/4 flanges, and uncoated.

 
These HTC coated Tork-StepTM Hedders are backed by a lifetime warranty against manfufacturing defects, and the coating is gauranteed for 5 full years.

The parts in this section employ Hedman's HTC Ceramic-metallic thermal coating for the ultimate protection against the elements, and keep under hood tempteratures down.

Construction of HTC coated Tork-StepTM Hedders is backed by a limited lifetime warranty against manfufacturing defects, and the coating is guaranteed for 5 full years.

Proud to Say, Made in U.S.A.!, since 1954.
