LT Ceramic Coated Long Tube Headers for 1964-1967 A-Body Chevelle El Camino GTO Cutlass Skylark
For LT engine conversions in classic 1964-1967 A body models such as the Chevelle, El Camino, GTO, Tempest, Cutlass, 442 and Skylark, the 1-7/8 ceramic coated long tube headers deliver a tailored fit that overcomes tight frame rail clearance and high underhood heat. Built from mild steel and finished in a multi layer ceramic coating the tubes reflect radiant energy back into exhaust pulses to preserve engine bay components. Precision CNC formed flanges match factory port layouts and include composite gaskets plus grade eight bolts for a reliable seal under vibration and thermal cycling. With optimized tube diameter these headers promote effective scavenging for stronger torque delivery across the rev range while resisting corrosion and chipping over extended service intervals.
Ceramic Coating Dynamics in LT Swap Headers
The multi layer ceramic coating applied to the 1 7/8 inch long tube headers serves more than a cosmetic purpose. By reflecting radiant heat back into the exhaust stream, it lowers underhood temperature and protects fragile wiring and hoses in tight engine bays. Heat retention also enhances exhaust pulse velocity for more effective scavenging, contributing to smoother torque delivery. This specialized finish resists chipping and corrosion during repeated thermal cycles, ensuring consistent performance.
CNC Formed Flange Precision for Factory Port Mating
Each 3/8 inch thick flange is cut and milled on a CNC platform to match original engine port patterns. Uniform surface contact combined with supplied composite gaskets and high-grade bolts creates a seal that resists leaks under vibration and thermal stress. Installers report straightforward alignment with minimal fuss, reducing the need for repeated bolt tensioning. This precise interface supports consistent exhaust flow and maintains seal integrity throughout demanding driving conditions.
Optimized Tube Geometry for Enhanced Scavenging
Careful tuning of tube diameter and length improves the natural scavenging effect critical for LT swaps. The straight long tube layout delays pulse merging until the collector, minimizing backpressure and boosting low end torque. Retaining thermal energy within the exhaust stream sustains higher gas velocity for responsive throttle feel across the entire rpm range. Welds made with MIG methods ensure bead consistency and fatigue resistant joins that hold under constant vibration.
Mild Steel Construction Backed by American Craftsmanship
Constructed from premium mild steel, these headers deliver the flexibility required to navigate tight frame rails on classic A body chassis. The steel's inherent toughness handles heat cycling and road vibration without cracking. Backed by domestic manufacturing standards, each set is assembled and inspected to confirm fit and finish. This homegrown approach guarantees reliable long term service in vintage LT engine builds while supporting American industry.
Designed for precise installation and lasting performance in LT engine conversions.
