Description

Part #: 78503

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. These headers use Hedman's patented TIGHT TUBES chamshell-style collector that allows for a low-profile header design, while still providing beneficial exhaust flow improvement over factory manifolds.

These BLACK-MAXX coated, TIGHT-TUBES headers fit a variety of 1967-1974 MOPAR passenger cars powered by Chrysler'S 273-360 LA engine (inline port port pattern only). Included in this list of popular models are 1970-74 Dodge Challenger, '67-74 Plymouth Barracuda, '66-74 Dodge Charger, '68-74 Plymouth Roadrunner 67-76 Dart, Duster, Super Bee and Valiant (check the application listings for exact fitment). The flat-style collector also makes these headers ideal for SB Chrysler equipped street rods and custom projects. These headers fit both manual and automatic transmission models, however, a mini-starter must be used, and modification to the shift linkage may be required. The smooth 1-5/8 in. tubes flow into the large, yet flat, collector, and provide improved exhaust flow, over factory manifolds, to let your Chrysler 273-360 (LA) engine produce additional horsepower and torque.

Each set includes a pair of header and collector gaskets, header flange bolts and collector bolts.

Hedman Hedders is so confident in the quality of its headers that these headers are factory backed by a Limited Lifetime Warranty. These headers have a high temperature, SATIN-BLACK ceramic finish that resists corrosion, and can withstand temperatures up to 1400 degree F. This finish is covered by a 5-year factory warranty, in addition to Hedman's standard lifetime header warranty.

Features:

  • The Lowest Profile Header On The Market
  • The Flat, Clamshell Style Collector Has an Extremely Low Profile So they'll Fit in Nearly Any Street Rod or Custom Build With Little Clearance.
  • The High Volume Flat Collector Offers Improved Exhaust Flow For Far Superior Performance Over Classic Block Hugger Models.
  • Includes Classic, 3-Bolt Gasket-Style Header Collectors, Mounting Hardware, Gaskets and Reducers (exhaust adapters)
  • Limted Lifetime Warranty On Construction, Five Year Warranty on Factory-Applied Header Coating!
  • Proud To Say, Made In The USA, Since 1954!
