1-7/8in Ceramic Coated LT Long Tube Headers for 1964-1967 A-Body Chevelle/El Camino
If you are fitting an LT powerplant into a 1964 to 1967 A-body Chevelle or El Camino this header set resolves frame rail clearance issues and lowers underhood temperatures. A layered ceramic finish retains exhaust energy within the tubing while reflecting radiant heat back into the flow and away from sensitive wiring hoses and paint surfaces. Each flange is CNC machined from 3/8 inch steel plate to match factory LT port dimensions for a reliable leak proof seal through repeated thermal cycles. Crafted from mild steel with fatigue resistant welds these headers slip into Chevelle, El Camino, GTO, Cutlass and Skylark models with precise alignment and dependability in every LT swap.
Ceramic Coating and Underhood Heat Management
Featuring a layered ceramic coating applied in an even thickness to the 1-7/8in headers, this finish does more than shield metal from high temperatures. It reflects radiant heat back into the exhaust pulses to preserve energy within the flow path and lower the overall temperature under the hood. With reduced heat soak, sensitive components such as wiring harnesses, hoses and paintwork remain protected during extended operation. The thermal barrier also sustains gas velocity through the primary tubes, enhancing torque output in the low and mid rpm ranges where everyday drivability matters most. Across hundreds of heating and cooling cycles the ceramic surface resists corrosion, chipping and flaking, ensuring reliable performance over the life of the swap. Its durability makes it a critical factor in maintaining consistent engine bay temperatures under spirited use.
Precision Machined Flanges for Reliable Seals
The flanges are crafted from three eighths inch mild steel plate and precision machined to original LT port dimensions, delivering an exact match to factory head surfaces. This process yields a uniform contact face that works in conjunction with composite gaskets and grade eight fasteners to secure a seal that endures vibration and temperature variations. Installers will note simplified alignment as each port pattern lines up without manual adjustment, reducing installation time and minimizing the need for follow-up torque checks. A reliable seal prevents exhaust leaks, which can cause performance losses and elevate underhood noise levels. This engineering focus ensures sustained exhaust flow and quiet operation for daily driving or spirited runs.
Engineered Tube Layout Enhancing Scavenging
The headers use 1-7/8in diameter tubing cut to specific lengths that support tuned exhaust scavenging for LT engines. By delaying pulse merging until after each cylinder has expelled its exhaust charge, the design harnesses low speed torque gains and smoother throttle response without the drawback of pressure buildup in the collector. This geometry aligns with the engine's firing order and stroke characteristics, resulting in a broader torque curve across the rpm band. Welds created with high quality MIG equipment form consistent penetration and a smooth bead profile that resists fatigue from road induced stress. The integrity of these seams preserves exhaust flow characteristics and reduces the risk of cracks over time.
Mild Steel Tubing and Weld Quality
Constructed from domestic mild steel tubing, these headers offer a balance of rigidity and flexibility essential for the tight frame rails of 1964 to 1967 A-body chassis. The steel resists cracking under the repeated expansion and contraction of thermal cycling, while maintaining enough pliancy to absorb chassis movement without compromising alignment. All tubes undergo a careful inspection process in the USA to verify straightness and uniform wall thickness before assembly. Welds are examined for penetration and consistency, ensuring each header meets stringent quality standards. The result is a direct bolt-in fit for Chevelle, El Camino, GTO, Cutlass and Skylark models that supports long engine life in any LT conversion.
Designed to fit seamlessly into your A-body Chevelle or El Camino chassis this ceramic coated header set ensures reliable exhaust flow and manageable underhood temperatures for lasting durability in LT swaps.
