1-7/8 Ceramic Coated LS Mid-Length Headers for 1968-1972 A-Body
When fitting an LS engine into a 1968 to 1972 A Body, these 1 7/8 inch ceramic coated mid length headers resolve tight clearance issues between the frame rails and floor pan while enabling efficient exhaust flow across the rpm band. Constructed from mandrel bent steel tubing with three eighth inch flanges, the headers match the LS cylinder head bolt pattern to maintain a leak proof seal and simplify installation by removing the need for adjustment shims. The ceramic barrier coating locks heat inside the primary tubes, lowering underhood temperatures and helping preserve intake charge density for stronger low rpm torque in classic A Body engine bays. Since these headers bolt directly to popular LS swap mount kits, there is no bracket fabrication or gasket grinding required, so installers can concentrate on calibration rather than fitment challenges.
Durable Steel Tubing Enhanced by Ceramic Barrier Coating
These mid length headers are fabricated from heavy gauge steel tubing selected for its ability to withstand repeated thermal cycles and resist warping under high exhaust temperatures. Precision mandrel bending preserves a uniform internal diameter throughout each bend to avoid flow restrictions and maintain efficient pulse scavenging. A factory applied ceramic barrier coating seals the tube exterior, reflecting radiant heat back into the exhaust stream and significantly lowering under hood temperatures. This heat containment helps preserve intake charge density for stronger low rpm torque while protecting nearby engine bay components from heat damage. Over time the silver coating also provides corrosion resistance against moisture and road debris, ensuring long term durability and a fresh appearance.
Precision Flange Interface Ensuring a Leakproof Cylinder Head Seal
Each header flange measures three eighths of an inch in thickness and is machined flat to match the LS cylinder head bolt pattern with exacting accuracy. This rigid interface eliminates common gasket leaks by providing a consistent sealing surface that resists deformation under thermal expansion and exhaust backpressure. By aligning perfectly with the factory head ports there is no need for adjustment shims, reducing installation time and avoiding post fitment rework. The precise flange to head connection clamps the gasket evenly across its entire surface, preventing exhaust gas escape and unwanted noise. Installers benefit from the included gaskets and hardware, which meet original equipment specifications for reliable sealing in classic A body engine bays.
Optimized Primary Tube Diameter and Routing for Torque Delivery
The primary tubes feature a 1.875 inch internal diameter, chosen to strike an ideal balance between exhaust gas velocity and volume. This dimension supports strong low and mid rpm torque by enhancing scavenging effects while still accommodating high rpm flow for peak power. Smoothed transitions at the merge collector further prevent turbulence and reduce pressure spikes, promoting a steady backpressure profile across the entire rev range. The routing of each tube is carefully engineered to navigate the tight confines between the frame rails and floor pan of 1968 to 1972 A body chassis without requiring modifications. When exhaust pulses exit the collector they converge into a deep and melodic tone that complements the classic muscle car soundtrack.
Seamless Fit with LS Swap Mount Kits for Streamlined Installation
These headers are designed to bolt directly to widely available LS engine swap mount kits, aligning with factory frame brackets to remove guesswork from bracket fabrication and welding. Critical attachment points on the header and frame match precisely, ensuring a secure fit that resists movement under torque loads and vibration. The inclusion of gaskets and grade specific bolts that comply with original equipment standards simplifies the build process, allowing technicians and home builders alike to focus on tuning rather than basic fitment issues. This plug and play approach not only speeds up the conversion project but also preserves undercarriage integrity by eliminating the need for grinding or clearance trimming. The result is a neat engine bay layout and straightforward access for maintenance in classic GM A body vehicles.
