Conversion Swap Long Tube Headers for Buick Chevrolet GMC (1964-1972) 4.8L 5.3L 5.7L 6.0L 6.2L Engine

High-Flow LS Swap Long Tube Headers for 1964-1972 GM Classics

Who Is This For? This kit is designed for builders and enthusiasts performing a Gen III or Gen IV LS engine conversion into classic GM platforms. Whether you are working on a Chevelle, Camaro, or a vintage C10, these headers provide the necessary clearance and flow for modern powerplants.

The Clearance Challenge: Fitting a modern 4.8L to 6.2L engine into a chassis designed decades ago usually results in steering shaft interference and poor ground clearance. Standard manifolds often choke performance, while low-grade headers eventually warp at the flange, causing persistent exhaust leaks.

The Engineering Solution: These BENSON Tuning long tube headers are constructed from brushed T304 stainless steel, featuring heavy-duty 3/8" CNC-machined flanges to prevent warping. With 1 3/4" primary tubes and 3" outlets, they are optimized for engines ranging from the LS1 and LS6 to the high-displacement LS7, ensuring your swap breathes as efficiently as possible.

The Comparative Edge

• Full T304 stainless steel construction provides superior heat management and rust resistance compared to painted mild steel.
• TIG and MIG welded joints offer structural integrity for high-vibration environments.
• Integrated O2 sensor bungs on the starter tubes allow for immediate ECU feedback without custom fabrication.
• Thick 3/8" head flanges ensure a flat, leak-free seal against the cylinder head.
