1964-1967 A-Body LT Ceramic Coated Long Tube Headers for Chevelle El Camino GTO Cutlass Skylark
If you are tackling an LT engine swap in your classic A Body from 1964 to 1967 this 1 7/8 inch ceramic coated long tube header set addresses tight frame rail clearance and helps cut underhood temperatures. Built with CNC formed flanges that match original ports these headers provide a reliable leak free seal and streamline exhaust flow for stronger low and mid range torque. Crafted from mild steel with durable welds and a layered finish that retains exhaust energy the design supports sustained performance and fits Chevelle El Camino GTO Cutlass and Skylark models precisely. This configuration also reflects radiant heat back into exhaust pulses helping protect wiring hoses and paint inside the engine bay during spirited driving.
Ceramic Coating Efficiency for Underhood Temperature Control
The multi layer ceramic finish applied to each 1 7/8 inch long tube works beyond surface protection to manage heat beneath the hood. By reflecting radiant energy back into exhaust pulses, this coating lowers the temperature in the engine bay and safeguards wiring, hoses, and paint from heat damage. Retaining exhaust energy within the tubing also maintains gas velocity, which enhances torque delivery in the low and mid rpm range. Over repeated thermal cycles the ceramic layer resists corrosion and chipping, ensuring consistent performance and reliable protection through seasons of spirited driving.
CNC Precision Flange Fabrication for Leak Resistance
Each flange is crafted from 3/8 inch mild steel plate and CNC machined to mirror the original LT port pattern with exacting accuracy. This precision ensures an even, full-length contact surface that works in concert with composite gaskets and grade eight bolts to form a seal impervious to vibration and thermal cycling. Installers benefit from straightforward alignment and minimal post-installation adjustment, reducing the need for repeated torque checks. The result is a leak free join that sustains optimal exhaust flow and service intervals.
Optimized Tube Geometry and Welding Integrity for Enhanced Scavenging
The 1 7/8 inch tube diameter and carefully calibrated length are designed to harness natural scavenging effects, pulling exhaust gases through the collector without pressure buildup. By delaying pulse merging until after each cylinder has expelled its charge, the long tube layout delivers stronger torque at lower engine speeds and a more responsive throttle feel. Premium MIG welds form consistent, fatigue resistant beads that stand up to chassis flex and road vibration, preventing premature cracks and preserving exhaust efficiency over time.
Mild Steel Construction for Classic Chassis Fit and Durability
These headers are built from domestic mild steel chosen for its balance of strength and flexibility, a vital combination for navigating the tight frame rails of 1964–1967 A-body platforms. The material resists cracking under repeated heat cycling and road impacts, while detailed inspection in the USA ensures perfect tube alignment and weld quality. This focus on manufacturing control guarantees a direct fit on Chevelle, El Camino, GTO, Cutlass, 442, and Skylark models and underpins long term durability in any LT engine swap.
These headers offer precise fit and lasting performance for your LT engine installation, backed by quality materials and craftsmanship.
