1964-1967 A-Body Ceramic Coated Long Tube Headers for Chevelle/El Camino/GTO/Tempest/Cutlass/442/Skylark
The 1964 to 1967 A-Body 1 and 7/8 inch LT Ceramic Coated Long Tube Headers are designed to address tight clearance and heat management when swapping an LT engine into a classic Chevelle, El Camino, GTO or Skylark. Mild steel tubes are covered in ceramic coating that reflects radiant heat back into the exhaust stream while resisting chipping and corrosion over repeated thermal cycles. Supplied gaskets and bolts pair with thick 3/8 inch flanges to create a precise fit and leak resistant seal, simplifying installation and helping maintain a neat engine bay. Manufactured in the USA, these headers support a dependable installation for any A-body swap project.
Advanced Ceramic Coating for Heat Control
The ceramic layer applied to the 1 7/8 inch header tubes reflects radiant heat back into the exhaust stream and significantly reduces underhood temperature. Multiple coating passes build a dense shell that resists chipping and corrosion through repeated heating cycles. By retaining more energy in the exhaust pulses, scavenging benefits from increased velocity, which helps torque delivery across the engine's power band. Cooler engine bays also protect wiring, hoses and other components from premature heat damage.
Precision Flange Engineering for a Leak Free Seal
Each header flange is CNC formed at a thickness of 3/8 inch to match the factory port layout on Chevelle, El Camino, GTO, Tempest, Cutlass and Skylark models from 1964 to 1967. This exact alignment ensures uniform contact and, when used with the supplied composite gaskets and high grade bolts, creates a reliable seal that resists leaks under vibration and thermal expansion. Installers appreciate how the precise fit streamlines torque procedures and minimizes the need for retightening after initial break-in.
Mild Steel Construction for Enduring Strength
Fabricated from premium mild steel tubing, these long tubes balance durability with formability to withstand high exhaust temperatures and pressure pulses. MIG welds at each junction produce smooth, consistent beads that resist fatigue from vibration and thermal cycling. The chosen 1 and 7/8 inch tube diameter optimizes flow characteristics for LT series engines while fitting within tight frame rails of classic muscle cars. Manufactured in the USA, this assembly delivers a dependable foundation for any LT engine swap project.
