1973-1977 A-Body 1-7/8in Ceramic Coated LS Long Tube Headers
When your project calls for uncompromised exhaust flow in a classic Chevy A body swap the 1973-1977 A body LS 1-7/8 Ceramic Coated Long Tube Headers deliver a direct fit solution that clears factory restrictions. Designed to pair seamlessly with LS mount kits, they ensure consistent torque gains and smoother throttle response across the RPM range. Built from mild steel with a ceramic finish and featuring a 3/8 inch thick flange, these headers maintain thermal stability and prevent leaks under demanding conditions.
Advanced Ceramic Finish for Thermal Stability
The ceramic coated finish on these headers acts as a barrier against heat soak into the engine bay while maintaining exhaust gas temperatures for improved scavenging. By reflecting radiant heat the coating helps keep underhood components cooler and reduces heat related wear on the header material. This thermal barrier also aids in sustaining exhaust velocity which contributes to consistent performance across varying engine loads and rpm ranges.
Optimized 1.875 Inch Tube Design
With 1.875 inch diameter primary tubes the long tube configuration reduces back pressure to unlock greater horsepower and torque output. The straight smooth path allows exhaust pulses to exit more quickly which improves throttle response and breathing efficiency. This geometry is especially effective in LS engine swaps where factory manifolds often restrict flow under mid to high rpm conditions.
Robust Three Eighths Inch Flange for Leak Free Sealing
The three eighths inch thick flange provides a solid mating surface against the cylinder head to prevent exhaust leaks that can rob power and cause noise. This extra material mass ensures the flange remains flat and resistant to warping under heat cycling. The result is a reliable seal that holds up to repeated startup and shutdown cycles without the need for retorquing.
Simplified Integration with Swap Mount Kits
These long tube headers are tailored to work with popular LS engine swap mount kits offering a near bolt on installation. The precision alignment of the collector exit and flange bolt pattern takes the guesswork out of fabricating or modifying engine bay components. This direct compatibility allows builders to spend more time tuning and less time fitting exhaust hardware for a smoother project timeline.
