Hedman Hedders has been manufacturing quality headers in the USA since 1954, and they've been manufacturing long and mid-length tube headers for 1967-87 Chevy/GMC C10 / C15 pick-up trucks for decades, so designing a good fitting, great performing set of headers for the popular LS engine swap was a piece of cake.
Each set uses smooth flowing, CNC mandrel bent tubes, that are hand-welded to ensure each pair is identical to the next. From head flange to ball collector, these headers are 100% T304 Stainless Steel construction, and come with a factory-applied BLACK-MAXX satin black ceramic coating that offers thermal protection up to 1300 F degrees! 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 Camaro, Firebird, Nova or Ventura's 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 header construction is factory backed by a Limited Lifetime Warranty, and factory applied ceramic coatings are covered for a full five years.
