1-7/8-inch Ceramic Coated Long Tube Headers for 1973-1977 A-Body LT Swaps
Swapping an LT engine into a 1973 to 1977 A body often runs into clearance and heat management issues under the hood, and a header set must match tight spaces while controlling temperatures. These ceramic coated long tube headers feature 1 7/8 inch primaries and sturdy 3/8 inch flanges that align precisely with factory exhaust ports for a leak resistant seal. With CNC formed bends, a multi layer ceramic finish, and included V band clamps and gaskets, installation stays straightforward and underhood temperatures remain in check to protect wiring and hoses in LT engine swaps.
Multiple layer ceramic finish controls underhood temperatures
The ceramic coated headers feature multiple uniform layers that form a hard shell to reflect radiant heat back into the exhaust path, significantly reducing underhood temperatures. By retaining heat inside the tubes, the design boosts exhaust gas velocity for improved scavenging and stronger torque delivery throughout the rpm range. The tough finish resists abrasion and thermal cycling without chipping, ensuring consistent performance over repeated use. This targeted heat management also protects nearby wiring, hoses and sensors from excessive thermal stress, helping to maintain reliable engine operation.
CNC formed flanges ensure leak free joint
Each primary tube is CNC formed to match factory LT engine ports with millimeter accuracy, producing a flush surface that minimizes gaps and misalignment. Paired with the supplied V band clamps and composite gaskets, this precise fit prevents exhaust leaks even under constant vibration and heat expansion. Installers benefit from simplified torque procedures and a reduced need for retightening after initial use, while the leak free seal maintains consistent backpressure for optimum performance and quiet operation.
Mild steel tubes deliver crack resistant durability
Constructed from premium mild steel, these headers balance ductility and strength to withstand repeated heating and cooling without cracking. The smooth tubular bends minimize sharp turns and surface disruptions, promoting uninterrupted flow and reducing stress points. Welds executed with a robust MIG process produce clean, consistent beads that resist fatigue over thousands of heat cycles. Together, these features provide a durable assembly capable of enduring demanding street or track conditions.
Complete hardware kit speeds installation
This header set includes all necessary V band clamps, composite gaskets and high grade bolts to streamline the fitment process and eliminate extra parts sourcing. By offering every mounting component in one package, installers avoid downtime and trips to the parts store. The V band clamp system allows for quick adjustments and easy removal for service, while the comprehensive kit ensures a tidy engine bay and faster overall assembly.
These ceramic coated long tube headers deliver precise fit, durable construction and straightforward installation for dependable LT swap performance.
