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 Chevy Tri-Fives for decades, so designing a good fitting, great performing set of headers for popular LS engine swaps is nothing new.
These long tube LS swap headers fit 1955-1957 Chevy Tri-5 Cars (150, 210, Belair, Nomad). They have a mild steel construction, and use smooth flowing, 1-3/4 in. diameter, CNC mandrel bent tubes that are hand-welded to ensure each pair is identical to the next. 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.
