Headers For Installing An LS Engine into a 1963-82 CHEVY CORVETTE (C2, C3); 1-3/4 in. Diameter, Mid-Length Tubes; 3 in. Ball/Socket Collector- Uncoated, Mild Steel Construction
Hedman Hedders has been manufacturing quality headers in the USA since 1954, and they've been manufacturing long and mid-length tube headers for 1968-82 Chevy Corvette models for decades, so designing a good fitting, great performing set of headers for the popular LS engine swap. Each set uses smooth flowing, 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 Hedman's unique, gasketless ball and socket collector design allows your Corvettes exhaust system to bolt up, even if it is not perfectly aligned with the header collectors. Hedman is so confident in the quality of its headers that these headers are factory backed by a Limited Lifetime Warranty.
