1-7/8 Ceramic Coated LT Long Tube Headers for 1971-1976 B-Body Impala/Caprice
When swapping an LT motor into a 1971-1976 Impala or Caprice B Body, maintaining factory port alignment and managing exhaust heat head on can make or break a build. These 1971-1976 B Body LT Series 1 7/8 inch Ceramic Coated Long Tube Headers combine precision CNC formed flanges that seal against the cylinder head and a layered ceramic finish that traps heat inside the tubes to improve scavenging and lower underhood temperatures. Installers also receive all required gaskets, bolts and V band clamps in one kit for a smoother start to any LT swap project.
Layered Ceramic Coating for Advanced Thermal Control
The 1 7/8 inch diameter tubes are finished with multiple layers of ceramic that reflect radiant heat back into the exhaust stream, significantly enhancing scavenging efficiency. By keeping thermal energy inside the header walls, this coating reduces underhood temperature spikes and shields nearby hoses and wiring from prolonged heat exposure. In tight engine bays of 1971–1976 Impala and Caprice B Body applications, that temperature reduction can prevent premature aging of rubber and plastic components. The rigid ceramic shell also resists abrasion and resists flaking over repeated thermal cycles, delivering consistent performance mile after mile.
Precision CNC Flanges for Leak Resistant Sealing
Each flange is computer numerically controlled to a thickness of 3/8 inch and machined to match the LT engine port pattern on 1971 through 1976 B Body cylinder heads. This level of precision ensures perfect face contact, virtually eliminating warpage and gasket failures under high torque load. When paired with the supplied composite gaskets and secure V band clamps, the design maintains a uniform seal through constant vibration and heat expansion. Installers benefit from fewer retorque checks and a reliable exhaust path that stays leak free even during spirited driving.
Premium Mild Steel Tubing with Uniform MIG Welds
These long tubes are crafted from domestic mild steel selected for its balance of tensile strength and malleability, allowing smooth mandrel bends without altering the internal diameter. Smooth MIG welds are applied at each joint to create uniform, fatigue-resistant seams that endure the repeated expansion and contraction of heat cycles. The combination of consistent bore and robust weld integrity promotes steady exhaust flow, minimizing back pressure. Whether driven on the street or pushed on the strip, these headers deliver the durability and consistent performance demanded by LT engine swap projects.
Comprehensive Hardware Kit for Streamlined LT Swap
This header set arrives complete with composite gaskets, high grade bolts and V band clamps so installers can start work immediately without sourcing additional parts. Each fastener is sized to the precise specifications of the cylinders and header flanges, ensuring correct torque application and reducing the risk of installation errors. The all-in-one package approach cuts assembly time in a home garage or professional shop and helps maintain a tidy engine bay layout. By delivering every required component in a single kit, the design simplifies the LT engine swap process and instills confidence in fit and finish.
These headers deliver precise fit reliable thermal control and streamlined installation for your LT swap project.
