1968-1972 A-Body LS Ceramic Coated Long Tube Headers for Chevelle GTO Cutlass Skylark
Swapping an LS powerplant into a classic A Body chassis often exposes clearance and fit issues that standard manifolds cannot solve. These long tube headers feature mandrel bent tubes with a 1-7/8 inch bore and a ceramic coat to optimize exhaust flow and manage underhood heat. They align precisely with popular mount kits for Chevelle, GTO, Cutlass and Skylark models to streamline installation and eliminate fitment headaches. With sturdy steel flanges that seal tightly, they deliver consistent performance and reliable durability drive after drive.
Enhanced Gas Flow from Mandrel Bent 1-7/8 Inch Tubes
These headers employ precision mandrel bending to maintain a smooth interior profile throughout the 1-7/8 inch primary tubes, eliminating the turbulence and backpressure common with crush-bent designs. The consistent bore ensures exhaust pulses merge seamlessly, improving scavenging efficiency and translating into stronger throttle response and better mid-range torque. This optimized flow path supports more complete cylinder evacuation during each exhaust stroke, boosting overall engine output without resorting to radical cam or tuning changes.
Ceramic Thermal Barrier for Underhood Heat Control
The silver ceramic coating serves as a robust thermal barrier that reflects radiant heat back into the exhaust stream, reducing underhood temperatures and safeguarding nearby components. By insulating the steel tubes, the finish slows heat transfer to the engine bay, minimizing heat soak into intake and wiring harnesses. Moreover, the ceramic layer resists corrosion and abrasion, preserving both appearance and performance through repeated temperature cycles.
Precision Fitment to Streamline Installation
Specifically crafted for 1968-1972 A-Body chassis with an LS powerplant, these headers align flawlessly with popular mount kits for Chevelle, GTO, Cutlass, and Skylark models. Exact flange bolt patterns and tube clearances reduce trial-and-error adjustments, saving installation time and preventing interference with frame rails or steering linkages. This vehicle-specific design ensures a secure, leak-free seal without the need for excessive shimming or aftermarket modifications.
Robust Steel Flanges for Leak-Proof Sealing
Fabricated from premium mild steel, each header flange is a full 3/8 inch thick to resist warping under high heat and clamping forces. The added mass and rigidity ensure even gasket compression, creating an airtight seal that prevents exhaust leaks and preserves consistent power delivery. This sturdy foundation also aids in precise alignment when mating to collectors or mid-pipes, maintaining uninterrupted flow through the entire exhaust system.
