1968-1972 A-Body Ceramic Coated Mid-Length LS Headers
When installing an LS engine into a 1968 to 1972 A Body chassis, these ceramic coated mid length 1 7/8 inch headers ensure perfect alignment with factory mounts. Constructed from heavy gauge steel with three eighths inch flanges, they resist warping under heat and maintain a leak proof seal. Precision mandrel bends guide exhaust gases smoothly through each curve and into the collector for crisper throttle response in everyday driving. Lower underhood temperatures protect intake components and wiring harnesses while preserving exhaust energy for consistent midrange torque across varied driving conditions.
Precision Mandrel Bending for Seamless Exhaust Scavenging
The tubing on these headers is formed using mandrel bending techniques that retain a constant internal diameter through each bend. By avoiding pinched or constricted sections, exhaust pulses flow without turbulence from the LS engine into the collector. This smooth transition accelerates scavenging, drawing spent gases out of the cylinders more efficiently during every exhaust stroke. The result is crisper throttle response and a broader midrange torque band exactly where street drivers need it most. Whether navigating city traffic or cruising on the highway, precision bends translate to more linear power delivery in your classic A Body swap.
Steel Construction and Thermal Barrier Coating for Underhood Protection
Crafted from heavy gauge steel, these headers withstand the extreme temperatures generated by a modern LS powerplant. The silver ceramic barrier applied to each tube reflects radiant heat back into the exhaust path, reducing underhood temperature and protecting surrounding components. Wiring harnesses, intake manifolds and sensors all benefit from a cooler engine bay environment, minimizing the risk of heat soak damage. At the same time, the coating preserves exhaust gas energy to maintain strong pulse velocity, ensuring consistent scavenging under varied driving conditions. Durable enough to resist chipping or flaking after repeated heat cycles, this treatment delivers reliable performance throughout the life of the swap.
Three Eighths Inch Flanges for a Leak-proof Cylinder Head Connection
Each flange is machined from robust steel plate to a thickness of three eighths inch, creating a flat and stable interface with the cylinder head. This rigidity prevents deformation under thermal cycling or vibration, so gaskets seat evenly and maintain a tight seal. Precision welding at the junction of flange and tube further reinforces structural integrity, reducing the chance of cracks or leaks over time. A secure exhaust path means the engine can maintain optimal backpressure levels, improving efficiency and power output. For enthusiasts installing an LS setup into a 1968–1972 A Body chassis, this flange design offers peace of mind with every drive.
Engineered for a precise fit and lasting performance in your LS swap, these headers offer reliable underhood temperatures and consistent torque delivery.
