Hedman | Mid-Length Headers For '66-74 MOPAR B & E-Body with 361-440 - Dodge / Plymouth 1966-1974

Hedman - Exhaust Header

Description

Hedman Hedders has been manufacturing quality headers in the USA since 1954, and classic musclecars is their specialty. Each set uses mild steel, smooth flowing, CNC mandrel bent tubes, that are hand-welded to ensure each pair is identical to the next. Hedman's unique, gasketless ball and socket collector design allows your Big Block Chrylser's exhaust system to bolt up, even if it is not perfectly aligned with the header collectors.

These uncoated, MID-LENGTH TUBE headers fit a variety of 1967-1974 MOPAR passenger cars powered by a Chrysler 361-440 B/RB engine. Included in this list of popular models are 1970-74 Dodge Challenger and Plymouth Barracuda, '66-74 Dodge Charger, '68-74 Plymouth Roadrunner and '67-70 Belvedere (check the application listings for exact fitment). These headers fit both manual and automatic transmission models, however, the use of a mini-starter is required. The smooth 1-3/4 in. tube design provides excellent exhaust flow to let your Chrysler 361-440 (wedge-style) engine breathe freely to produce more low-end horsepower and torque.

These headers are uncoated, and ship from the factory with a temporary black paint that will burn off when submitted to normal operating temperatures. For protection against the element and lower underhood temperatures, these headers are also available with a silver or black ceramic-metallic finish.

Each set includes a pair of gaskets, header flange bolts and collector bolts. No collector gasket is needed.

Hedman Hedders is so confident in the quality of its headers that these headers are factory backed by a Limited Lifetime Warranty.
