Hedman Hedders LS IN 64-67 A-BODY/'70-72 MONTE CARLO;1-3/4 X 1-7/8 IN. DIA, STEPPED LONG 45200

Hedman Hedders, along with its Hedman Husler race header division, have been building quality headers in the USA since 1954! Hedman has manufactured long and mid-length tube headers for classic cars, like the Chevelle, GTO, Monte Carlo and Impala for years, so designing a good fitting, great performing set of headers for popular LS engine swaps is nothing new.

These STEPPED long tube LS swap headers fit 1964-1972 GM A-Body cars, 1970-72 Chevy Monte Carlo, and 1977-1990 GM B-Body cars (Chevy Impala SS, Buick Roadmaster). They have a mild steel construction, and use smooth flowing, 1-3/4 in. x 1-7/8 in. diameter STEPPED TUBES that provide higher torque across the entire RPM range. The smaller tube diameter at the exhaust port increases back-pressure at low-RPM to improve low-end torque from the line, or out of the corner, while the larger diamter tube segment produces more torque as you reach Wide-Open throttle.

The stout 3/8" header flanges ensure a great seal that will resist warping, and the high-flow 3 in. race collectors ensure unimpeded exhaust flow for maximum performance.

Hedman Husler confidently backs these headers with a One year warranty. This part number ships from the factory with a raw mild steel surface.
