Precision-Flanged 1-7/8in Ceramic Long Tube Headers for '73-'77 A-Body LS

Optimized for LS swaps in 1973 to 1977 A body chassis, these 1-7/8in ceramic coated headers harness smooth long tube routing and a heavy 3/8 inch thick flange to boost horsepower and torque by cutting back pressure. High-grade steel with a thermal ceramic finish maintains optimal exhaust temperatures, prevents leaks and wards off corrosion for reliable performance.

Ceramic Coated 1-7/8 Long Tube Headers for 1973-1977 A-Body

For anyone swapping an LS powerplant into a 1973-1977 Chevy A-body and battling restrictive factory manifolds, the 1973-1977 A-body LS 1-7/8 Ceramic Coated Long Tube Headers deliver a direct fit solution. Designed with 1.875 inch primaries and a 3/8 inch thick flange, they maintain a precise seal to prevent exhaust leaks under demanding conditions. Crafted from mild steel and finished in ceramic, these headers reflect radiant heat to keep engine bay temperatures under control without sacrificing exhaust velocity. They align with popular LS mount kits to reduce fabrication time and let builders focus on tuning rather than fitment challenges.

Advanced Ceramic Coating for Heat Control

The ceramic coating on these headers serves as an effective barrier to radiant heat, reflecting thermal energy back into the exhaust stream and reducing underhood temperatures. By maintaining higher gas temperatures inside the primaries, the coating promotes stronger pulse scavenging for steadier performance across the rev range. This thermal shield also protects nearby wiring and components, helping prevent heat-related wear and tear over countless driving cycles. Builders will appreciate the balance between heat retention in the tubes and cooler engine bay conditions for a more reliable swap.

Optimized 1.875 Inch Tube Design

Matching the ideal flow characteristics for LS displacements, the 1.875 inch diameter primaries strike a balance between gas velocity and volume. The smooth, mandrel-bent paths minimize turbulence and back pressure, unlocking gains in both mid-range torque and top-end horsepower. This geometry is especially beneficial on vintage A-body frames where factory manifolds often choke the exhaust under load. The result is crisper throttle response and more consistent power delivery throughout the rpm band.

Heavy Duty Flange Design for Leak Prevention

Constructed from mild steel with a three eighths inch thick flange, these headers resist warping under repeated heat cycles to maintain a precise seal. The added mass at the head interface ensures the flange stays flat and mated to the cylinder head, virtually eliminating exhaust leaks that can diminish output and introduce noise. This robust approach means fewer retorque sessions and long-lasting reliability, even under rigorous driving conditions.

Engine Swap Compatibility with Mount Kits

Specifically tailored for use with popular LS engine mount kits, these headers align perfectly with existing bolt-on hardware to streamline installation. Precise flange bolt patterns and collector exit locations remove guesswork, allowing builders to focus on custom tuning rather than fabrication. The direct-fit nature of the design slashes install time and reduces the need for modifications, making it easier to finish projects on schedule.

Engineered for a precise fit and reliable performance, these headers are an excellent choice for your LS swap project.
