LT Ceramic Coated Long Tube Headers for 1964-1967 Chevelle El Camino GTO/Tempest Cutlass/442 Skylark
The 1964 to 1967 A body 1 7/8 inch LT Ceramic Coated Long Tube Headers tackle tight frame rail clearance and underhood heat, delivering a precise fit for LT engine conversions in classic Chevelle, El Camino and Skylark models. Built from mild steel and finished with a layered ceramic coating, they reflect radiant energy back into the exhaust pulses to protect engine bay components and maintain gas velocity for stronger torque. Each flange is CNC formed to factory port patterns and includes composite gaskets and grade eight bolts to ensure a reliable seal under vibration and thermal cycling. Together these headers promote effective scavenging across the rev range while resisting corrosion through extended service intervals.
Ceramic Coating Efficiency for Underhood Heat Control
The multi-layer ceramic finish on these 1 7/8 inch long tubes serves a key role beyond appearance. By reflecting radiant energy back into the exhaust pulses, the coating cuts underhood temperatures and shields wiring, hoses, and paint from excess heat. This internal heat retention also preserves gas velocity for smoother torque delivery at low and midrange rpms. Over repeated thermal cycles the ceramic layer resists chipping and corrosion, ensuring the coating remains intact and effective through seasons of spirited driving.
CNC Flange Precision for Reliable Port Sealing
Each flange is formed from 3/8 inch mild steel plate and machined on a CNC platform to match original LT port patterns with exacting accuracy. The uniform surface contact, combined with supplied composite gaskets and grade eight bolts, creates a seal that stands up to vibration and thermal expansion without leaks. Installers benefit from fast alignment and reduced fuss when tacking down the header to the block, cutting installation time and eliminating retorquing in service. This precise mating surface supports consistent exhaust flow and keeps maintenance intervals on schedule.
Optimized Tube Geometry for Enhanced Scavenging
The header tube diameter and length are tuned to harness natural scavenging, drawing exhaust pulses toward the collector without backpressure buildup. The straight long tube layout delays pulse merging until after each cylinder's exhaust event, promoting stronger low-end torque and a more responsive throttle feel throughout the rpm range. Premium MIG welds deliver uniform beads and fatigue resistance, preventing premature cracks when the chassis flexes during acceleration or cornering. This approach yields a balanced power curve tailored to street and strip applications.
Mild Steel Construction Built for Classic Chassis Fitment
Crafted from domestic mild steel, these headers combine strength and flexibility to clear tight frame rails on 1964 through 1967 A Body models. The material's toughness stands up to road vibration, heat cycling, and occasional ground contact without cracking. Proudly assembled in the USA, each header set undergoes inspection for tube alignment and weld integrity to guarantee a direct fit on Chevelle, El Camino, GTO, Cutlass, 442, and Skylark vehicles. This focus on material quality and manufacturing controls delivers a dependable foundation for any LT engine swap.
