1-7/8-inch Ceramic Coated Long Tube Headers for 1975-1979 X-Body LT Swaps
For enthusiasts fitting an LT block into a 1975 to 1979 X body chassis, finding headers with both precise alignment and open flow can make or break a swap project. These ceramic coated long tube headers, designed for LT engine swaps, deliver matched port geometry and three eighths inch flanges to ensure a leak free seal at the exhaust ports. V band clamps and composite gaskets are supplied to simplify installation and maintain tidy tubing runs within the engine bay. By reflecting radiant heat back into the exhaust stream, the ceramic coating also keeps underhood temperatures in check and promotes consistent scavenging throughout the rev range.
Advanced Ceramic Coating for Thermal Management
The headers are finished in a multi-layer ceramic coat that reflects radiant heat back into the exhaust stream and lowers underhood temperatures. This durable shell resists chipping and abrasion under repeated thermal cycles, ensuring the finish remains intact for years of service. By retaining more heat within the tubes, exhaust gas velocity increases and scavenging improves across the rev range. The net effect is a stable manifold temperature, reduced risk to nearby hoses and wiring, and more consistent power delivery throughout the powerband.
Precision CNC-Formed Flanges Ensure a Leak Free Seal
Each flange is CNC formed to match the factory X-Body exhaust port profile exactly, then machined to 3/8 inch thickness for uniform contact under torque. When combined with the included composite gaskets and V-band clamps, this precision fit eliminates port misalignment and minimizes exhaust leakage. Installers benefit from simplified torque procedures and fewer retorques after initial break-in, leading to a dependable seal that holds under vibration and thermal expansion.
Mild Steel Tubing and MIG Welds Deliver Structural Integrity
Fabricated from premium mild steel, the long tube headers balance strength with formability to withstand the rigors of high heat and pressure. A controlled MIG welding process produces smooth, fatigue-resistant beads at each joint, preventing cracks under repeated vibration. The carefully sized primary tubes optimize flow while handling the pressure pulses of an LT engine, resulting in a robust assembly that endures street and track use without compromise.
V-Band Clamps and Composite Gaskets for Streamlined Installation
The supplied V-band clamps and composite gaskets take the guesswork out of header installation by delivering consistent clamping force even on imperfect surfaces. This clamp-and-seal system accommodates thermal expansion without loosening, so assemblies stay tight through aggressive driving. High-grade hardware resists corrosion and makes alignment within a crowded engine bay straightforward, accelerating setup time and ensuring reliable performance from day one.
