1968-1972 A-Body Ceramic Coated Mid-Length LS Headers
Adapting an LS engine to a 1968 to 1972 A body chassis demands careful management of clearance and under hood heat and these ceramic coated mid length headers deliver a precise fit and durable build while addressing both. Heavy gauge steel primary tubes sized at 1 7/8 inch optimize exhaust pulse scavenging for a broader torque curve without compromising steering or crossmember clearance. The reflective ceramic barrier locks heat inside the exhaust path and shields wiring hoses and intake parts from radiant damage during spirited driving. Factory style flanges match original mounting points and included gaskets and hardware allow a bolt on fit without any fabrication.
Precision Scavenging with One and Seven Eighths Inch Primary Tubes
The optimized one and seven eighths inch primary tubes are calibrated to match the pulse characteristics of LS exhaust flow, promoting efficient scavenging across the rpm range. Consistent tube length and smooth mandrel bends balance pressure waves, resulting in a broader torque curve and more linear throttle response. Drivers will notice stronger midrange pull and improved highway cruising performance as back pressure is minimized. This level of precision in tube diameter and routing enables the engine to breathe freely under load, translating into measurable horsepower gains without sacrificing low speed tractability.
Ceramic Barrier for Underhood Heat Management
A high temperature ceramic coating forms a reflective layer that directs radiant energy back into the exhaust stream and away from sensitive components. This reflective ceramic barrier helps lower underhood temperatures, reducing the risk of heat soak on wiring, hoses, and intake plumbing during extended runs. By trapping heat within the exhaust path, the coating not only improves scavenging efficiency but also slows corrosion and fatigue of the steel substrate. Over time, this protective finish contributes to consistent performance and extended service intervals in demanding driving conditions.
Heavy Gauge Steel Construction for Lasting Strength
Fabricated from robust heavy gauge steel, these headers withstand the high pressures and temperatures generated by a modern LS small block. The steel's inherent rigidity maintains shape under thermal cycling, preventing premature distortion or cracking. Precision welding reinforces critical junctions, ensuring that each primary tube retains its designed profile even after repeated heating and cooling. This durable construction supports sustained horsepower delivery and provides the structural integrity needed for spirited driving without compromise.
Accurate Flange Geometry and Leak Free Sealing
Each flange is machined to a three eighths inch thickness to guarantee a perfectly flat mating surface where the header meets the cylinder head. This dimensional accuracy is critical for a reliable seal and prevents exhaust leaks that can erode performance or generate unwanted noise. Factory style bolt holes align directly with existing mounting points, enabling a clean bolt on installation that avoids frame alteration. Included gaskets and hardware ensure a complete setup, so enthusiasts can achieve consistent sealing and uninterrupted power delivery on both street and track applications.
Designed for a precise fit and reliable performance in any LS swap application on classic A body chassis.
