Ceramic Coated 1-7/8-inch LS Long Tube Headers for 1971-1976 B-Body
If you're swapping an LS engine into a 1971-1976 B-Body chassis these ceramic coated long tube headers address tight clearance and heat control challenges with precision fitment. Crafted from high grade mild steel the headers resist warping under thermal stress and feature a ceramic coating that helps to manage underhood temperatures. Installation hardware such as quality gaskets bolts and V-band clamps comes with the package to ensure a straightforward assembly and reliable exhaust sealing.
Precision Fitment for LS Engine Conversions
The long tube headers are shaped to align perfectly with LS engine exhaust ports and the 1971-1976 B-Body frame rails, reducing the guesswork in chassis clearance. This precision fitment cuts down installation time by ensuring that the header tubes and flange mating surface meet at the correct angle without modification. Built-in collector positioning matches factory mounting points, allowing installers to simply bolt on the included gaskets, bolts and V band clamps. The result is a streamlined assembly process that keeps your classic truck on schedule and avoids the need for custom fabrication.
Advanced Ceramic Finish for Underhood Temperature Control
The premium ceramic coating acts as a thermal barrier to trap heat inside the header tubing, reducing underhood temperatures and helping protect nearby wiring and components. By limiting heat transfer, the coating also minimizes radiant heat that can rob your intake charge of density. In addition to thermal benefits, the finish resists peeling and corrosion, extending the service life of the headers under repeated heat cycles. This temperature management is key to preserving power output and preventing heat-related fatigue in other engine bay parts.
Durable Steel Flange Design Ensuring Leak Proof Seal
Manufactured from high-grade mild steel, each flange is machined to a 3/8 inch thickness to provide a robust seal against exhaust leaks. This rigid flange thickness prevents warping under the intense heat and vibration of high rpm driving. Combined with Seal-4-Good gaskets and hardware that are sized precisely to the flange faces, the system maintains a leak proof seal over thousands of miles. Reliable sealing preserves exhaust scavenging efficiency and prevents performance losses caused by escaping gases.
1.875 Inch Tube Diameter Optimized for Exhaust Flow
The 1.875 inch primary tubes are sized to balance low-end torque with high-rpm horsepower, maximizing scavenging on an LS engine. This diameter improves flow velocity without sacrificing midrange response, translating to stronger throttle reaction and broader powerband. Smooth bends and uniform tube lengths contribute to consistent exhaust pulse timing, which enhances overall engine efficiency. Whether you are cruising or launching hard off the line, the optimized tube size delivers measurable gains in output.
