Exh Gskt Set Pro-Copper LS1/LS6 2.130 Dia Port

The Exh Gskt Set Pro-Copper LS1/LS6 2.130 Dia Port from SCE Gaskets is a professional-grade exhaust header gasket set engineered specifically for GM LS-series engines. These gaskets seal the critical interface between cylinder heads and exhaust manifolds, preventing exhaust leaks that compromise both performance and engine longevity. Built for LS1 and LS6 platforms with 2.130-inch round port sizing, this pair delivers the reliability demanded by serious engine builders, tuners, and DIY enthusiasts tackling high-performance builds or restorations.

Constructed from premium copper material, the Exh Gskt Set Pro-Copper LS1/LS6 2.130 Dia Port combines superior thermal conductivity with exceptional durability under extreme exhaust temperatures. Copper gaskets excel at conforming to port surfaces and maintaining a robust seal even when headers expand and contract during thermal cycling—a critical advantage over conventional composite gaskets in forced-induction and high-heat applications. The 2.130-inch port diameter matches OEM LS1/LS6 specifications precisely, ensuring perfect alignment and eliminating the risk of port mismatch that causes persistent exhaust leaks and power loss.

This gasket set is ideal for anyone installing performance headers, replacing factory exhaust manifolds, or performing cylinder head work on LS-series engines. Whether you're building a street machine, track car, or restoration project, proper header gasket selection prevents expensive exhaust system failure and ensures repeatable, leak-free performance. The pair format delivers both gaskets needed for left and right bank installation, streamlining the purchasing process and guaranteeing OEM-spec compatibility across all LS1 and LS6 applications.
