Ceramic Coated LT Mid-Length Headers for 1968-1972 Chevelle GTO Cutlass Skylark
If you are installing an LT small block into a 1968 to 1972 A body Chevelle, GTO, Cutlass or Skylark, these ceramic coated mid-length headers are engineered to deliver consistent exhaust routing and maintain factory port alignment. Precision CNC formed tubes and machined flanges guarantee a leak free seal under vibration and thermal stress while the ceramic barrier retains heat within the exhaust stream to improve scavenging and limit heat soak. Installation follows exact factory port spacing across all four models so you can bolt up without bending, trimming or shimming to your stock manifolds and frame rails. Built from mild steel with tight MIG weld beads, these headers resist fatigue during repeated heat cycles and hold their fit without extra shims or torque adjustments out of the box.
Advanced Ceramic Finish for Precise Heat Management
The multi layer ceramic coating on these one and seven eighths inch tubes creates a dense thermal barrier that reflects heat back into the exhaust stream. By sustaining higher gas temperatures, scavenging efficiency is improved throughout the entire rpm range, which helps preserve torque and peak output. At the same time, the coating reduces heat transfer to surrounding engine bay components, protecting wiring, hoses and intake parts from excessive warming. Over repeated thermal cycles the ceramic layers resist abrasion and chipping, ensuring consistent performance and appearance without fading or peeling.
Precision CNC Formed Flanges for Perfect Port Seal
Each flange is CNC formed and milled to a precise three eighths inch thickness to match factory port dimensions exactly. This exact fit eliminates alignment errors and prevents exhaust leaks under both vibration and thermal expansion. When installed with the supplied composite gaskets and V band clamps, the headers achieve a secure seal without the need for shims or excessive torque. The consistent flange geometry also ensures repeatable fitment during maintenance or future engine swaps, maintaining leak free operation on street and track alike.
Mild Steel Tubing and MIG Welded Joints for Lasting Durability
Constructed from premium mild steel, the tubing balances high strength with the flexibility needed for complex bends in a tight engine bay. Mandrel bending preserves a smooth internal profile, reducing turbulence and promoting uniform exhaust flow from each cylinder. Precision MIG welded joints fuse the tubes with solid, uniform beads that resist fatigue over countless heating and cooling cycles. This combination of material choice and welding technique yields a header assembly capable of withstanding high exhaust pressure and extreme thermal swings for reliable performance on both daily drives and competition events.
