1-7/8-inch Ceramic Coated Long Tube Headers for 1968-1972 A-Body LT Swaps
Installing these 1 7/8 inch ceramic coated long tube headers during an LT engine swap for a 1968 through 1972 A body ensures a precise fit and clean engine bay layout. Built with CNC formed tubes and robust 3/8 inch flanges the design holds factory port alignment and prevents leaks under vibration. A multi layer ceramic finish reflects radiant heat back into the exhaust stream keeping underhood temperatures lower and aiding exhaust scavenging across the powerband.
Multi Layer Ceramic Barrier for Consistent Heat Control
The ceramic finish on these 1 7/8 inch headers is built up in multiple layers to form a dense shell that resists chipping and abrasion under repeated thermal cycling. By reflecting radiant heat back into the exhaust stream, this coating helps maintain hotter gas temperatures for improved scavenging and more efficient flow through the powerband. At the same time, underhood temperatures stay lower, protecting nearby wiring, hoses, and intake components. Over time, the durable ceramic barrier continues to deliver consistent performance without flaking or fading.
CNC Formed 3/8 Inch Flanges for Exact Port Alignment
Each flange is CNC formed to factory port dimensions and machined to a precise 3/8 inch thickness, ensuring perfect contact with cylinder head exhaust openings. This exact fit eliminates misalignment and reduces the risk of leaks under vibration or thermal expansion. Combined with the supplied V band clamps, composite gaskets, and high grade bolts, installers achieve a secure, leak-resistant joint without tedious shimming. The result is a reliable seal that holds tight through spirited driving and frequent heat cycles.
Premium Mild Steel Tubing with Precision MIG Welds
These headers are constructed from quality mild steel tubing chosen for its strength and formability in demanding exhaust applications. The tubes are mandrel bent to maintain smooth, consistent bends that optimize flow, while precision MIG welding produces clean, uniform beads that resist fatigue. Mild steel's ability to absorb and dissipate heat prevents cracks that can emerge in stiffer alloys, ensuring long-term durability on both street and track. This combination of material and weld method creates a header assembly built to withstand high temperatures and pressure without compromise.
