68-72 Chevelle Headers w/LS Engine

The HEDMAN 68-72 Chevelle Headers with LS Engine Conversion are long-tube exhaust headers engineered for classic A-Body platforms running modern LS-series powerplants. This pairing delivers measurable performance gains by optimizing exhaust scavenging and reducing backpressure—critical advantages when retrofitting a high-efficiency LS engine into original 1968–1972 Chevrolet Chevelle chassis. The headers arrive complete with gaskets and mounting hardware, streamlining installation on LS conversion projects.

Built from steel with a black ceramic coating, these 1.75-inch primary tubes funnel exhaust into a 3-inch collector, matching the exhaust flow characteristics of LS engines that produce significantly more heat and volume than original small-block Chevrolet engines. The ceramic finish provides thermal management and corrosion protection in engine bays where underhood temperatures run higher with LS swaps. At 33.5 lbs per pair, the headers deliver structural rigidity without excessive weight penalty—important for handling characteristics in restored or restomod builds. The long-tube design maximizes ground clearance and minimizes header-to-chassis interference, a practical consideration when retrofitting modern engines into vehicles originally designed around carbureted or first-generation fuel-injected powerplants.

This header set targets restomod enthusiasts and performance builders undertaking LS conversions on second-generation Chevelles. Drivers pursuing both street and track applications benefit from the improved exhaust efficiency that supports LS engine output while maintaining compatibility with original body panels and suspension geometry. Compatibility with GM LS-series engines (including LS1, LS2, LS3, and related variants) positions these headers as a foundational component in the growing market for classic-to-modern powertrain swaps.

Long-tube headers for LS conversions remain the preferred choice over shorty designs when ground clearance and thermal management are priorities. The 3-inch collector diameter aligns with common LS exhaust system architecture, supporting seamless integration with aftermarket mufflers, cat-back systems, and performance tuning platforms popular in the restomod community.
