68-72 Chevelle Long Tube LS Swap HTC Hedders

The 68-72 Chevelle Long Tube LS Swap HTC Hedders from HEDMAN are purpose-built exhaust headers designed specifically for builders performing LS engine swaps into classic Chevelle muscle cars. These headers are ideal for those restoring a 1968–1972 Chevelle with a modern LS powerplant or upgrading an existing LS-equipped platform, addressing fitment and performance challenges commonly encountered in vintage A-body frames.

HEDMAN long-tube headers feature mandrel-bent primary tubes that optimize exhaust gas velocity and minimize turbulence across the full RPM range, resulting in improved scavenging efficiency and measurable gains in both power and throttle response. The HTC (High-Temperature Coating) finish protects against rust and thermal degradation while managing underhood heat, which is critical in tight Chevelle engine bays where radiant heat is a concern.

Serious LS swap enthusiasts who demand authentic fitment without compromise will appreciate the engineering precision of these headers. They are designed to integrate cleanly with modern LS oil pans and accessory mounting points specific to A-body chassis geometry, making them a valuable addition for any performance-driven Chevelle project.
