GM A-Body cars went through a transformation in 1978, and although GM re-designated rear-wheel drive A-Body models as G-Bodies beginning in 1982, the platform remained relatively unchanged until 1988. The 1978-88 A and G-Body segment contains some of the more iconic muscle cars of that era, making them prime candidates for an LS swap.
Hedman Hedders has been building exhaust headers in the USA since 1954, and their extensive experience shows in the construction of these 1-3/4" diameter, mid-length LS swap headers, designed specifically for installing the reliable, late-model powerplant into 1978-87 Caballero, Cutlass, El Camino, Grand Prix, and Regal, or 1978-88 Monte Carlo models.
Built from mild steel material and handcrafted in Hedman's Whittier, California manufacturing plant, these headers come complete with gaskets, small head header bolts, and exhaust collector adapter for attaching the headers to a 2-1/2 in. exhaust system. They have a durable, satin black ceramic-metallic finish to keep underhood temperatures down, increase exhaust speed to help with scavenging, and look good great at the same time. Also available with Hedman's HTC polished silver ceramic-metallic finish, or uncoated.
As with all Hedman Hedders, these headers are backed by a limited lifetime warranty, and the coating is covered for a full 5 years.
To ensure proper fit, we recommend the use of Trans-Dapt's engine and transmission swap mounts designed for you with these headers.
