1964-1967 GM A-Body LT Ceramic-Coated Long Tube Headers
If you are undertaking an LT engine swap into an A Body chassis, the 1964-1967 A-Body 1-7/8 LT Ceramic Coated Long Tube Headers deliver a precise fit and reliable exhaust routing while addressing tight frame rail clearances. Constructed from 1 7/8 inch mild steel tubing with multi layer ceramic coating, these headers feature 3/8 inch CNC formed flanges, MIG welded joints and include composite gaskets, high grade mounting bolts and V band clamps. Made in USA, they install effortlessly on Chevelle 1964-1967, El Camino 1964-1967, GTO/Tempest 1964-1967, Cutlass 442 1964-1967 and Skylark 1964-1967 models for consistent performance in every LT swap.
Engineered Fit for 1964 through 1967 A Body Chassis
The 1964 through 1967 A Body one and seven eighth inch ceramic coated long tube headers are purpose built for LT engine swaps in classic muscle applications. Designed in collaboration with MuscleRods mounting systems, these headers align precisely with factory torque mounts and engine crossmembers, ensuring accurate engine placement and optimal drivetrain angles. This targeted compatibility preserves original chassis geometry and prevents alignment stresses on engine mounts and accessories, reducing installation time and avoiding potential interference with steering and brake components.
Advanced Thermal Management
The multilayer ceramic barrier retains exhaust heat within the primary tubes, promoting vigorous gas flow and enhancing exhaust scavenging throughout the rpm band. By maintaining higher internal tube temperatures, these headers reduce underhood thermal load, which benefits wiring harnesses, intake manifold seals and other heat sensitive parts. The result is improved durability of surrounding components and consistent power delivery even under sustained high load driving.
Precision CNC Flanges
CNC formed three eighth inch flanges offer flat, uniform surfaces that yield leakproof port seals and a direct gasket interface. This precision approach eliminates exhaust leaks that can compromise torque curves and lead to erratic oxygen sensor readings. The sturdy flanges hold precise alignment for bolt passages, making it easier to achieve factory torque specs and maintain longterm sealing integrity without additional shims or modifications.
Robust Construction and U.S. Craftsmanship
Constructed from premium mild steel tubing, each header features fatigue-resistant MIG welds that endure aggressive heat cycles and vibration without cracking. The use of mild steel provides a balance of strength and malleability, allowing exact tube routing that conforms to chassis contours. Proudly made in USA, these headers undergo strict quality inspections to ensure consistency in tube wall thickness and weld penetration, delivering a durable component ready for daily driving or competition use.
