LT Ceramic Coated Long Tube Headers for 1968-1972 A-Body Chevelle/GTO/Cutlass/Skylark
When installing an LT engine into a 1968 to 1972 A-body Chevelle, GTO, Cutlass or Skylark these ceramic coated headers ensure perfect port alignment and a tidy engine bay layout. With CNC formed tubes and 3/8 inch flanges machined to factory specs the fit holds tight under vibration without leaks. A dense ceramic finish reflects heat back into the exhaust flow to lower underhood temperatures and improve scavenging across the powerband. Built from mild steel with multi layer coating these headers resist repeated thermal cycles for lasting reliability on street or track.
Multi Layer Ceramic Coating for Effective Heat Management
The multi layer ceramic finish on these 1 7/8 inch headers creates a durable thermal barrier that reflects radiant heat back into the exhaust stream. This reflection maintains hotter gas temperatures for improved scavenging, which helps sustain torque and power across the engine's rpm range. At the same time, the coating keeps underhood temperatures lower to protect wiring, hoses, and sensitive components. Over repeated thermal cycles, the dense ceramic layers resist chipping and abrasion, ensuring consistent heat control without flaking or fading.
CNC Formed 3/8 Inch Flanges for Perfect Port Alignment
Each flange is precision CNC formed and milled to a uniform 3/8 inch thickness, so it matches factory port dimensions exactly. This accuracy eliminates misalignment and prevents exhaust leaks under vibration and thermal expansion. When paired with the composite gaskets and V band clamps provided, installers achieve a secure seal without the need for shims or excessive torque. The result is a leak resistant joint that maintains its integrity through track days and street driving alike.
Robust Mild Steel Tubing and MIG Welding for Lasting Strength
Constructed from premium mild steel tubing, these headers offer an ideal balance of strength and formability for complex bends and tight clearances. Mandrel bending preserves a consistent internal diameter, reducing turbulence and promoting smoother exhaust flow. Precision MIG welds join each tube with clean, uniform beads that resist fatigue under repeated heating and cooling cycles. This combination of material and weld technique delivers a header assembly capable of withstanding high exhaust pressure and temperature without cracking over time.
