Hedman Hedders 66231 Details
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 you to bolt up, even if it is not perfectly aligned with the header collectors.
Hedman Hedders is so confident in the quality of its headers that these headers are factory backed by a Limited Lifetime Warranty.
