Exh Gskt Pro-Copper 1pk Buick 231 V6 Turbo WG

The SCE Gaskets Exhaust Header Gasket Pro-Copper for Buick 231 V6 Turbo is a premium copper exhaust manifold gasket engineered to seal the critical joint between cylinder head and exhaust manifold. This gasket features a 2.070 x 3.620 inch oval port design specifically matched to Buick V6 applications, including turbocharged variants. Pro-Copper construction delivers superior sealing performance and thermal cycling durability compared to standard composite gaskets, making it the preferred choice for engine builders and performance enthusiasts requiring reliable, long-term exhaust system integrity.

Copper exhaust gaskets expand and contract with engine heat cycles more effectively than fiber or composite materials, maintaining a consistent seal even under elevated boost pressures typical of turbocharged engines. The pro-grade copper composition withstands repeated thermal stress without degradation, reducing the risk of exhaust manifold leaks that compromise engine efficiency and create annoying exhaust noise. Installation is straightforward—this single-pack gasket replaces the stock unit at the manifold flange, and its precisely cut port dimensions ensure perfect alignment with OEM bolt patterns and port sizing on the 231 V6 platform.

This product is ideal for engine rebuilds, turbo installations, or manifold work where OEM gasket replacement is required. Whether performing routine maintenance, addressing an existing leak, or building a turbocharged small-displacement V6, the SCE Gaskets Pro-Copper exhaust header gasket offers the material quality and port-match precision that serious engine work demands. Included as a single gasket (one pack = one vehicle application), it provides the reliability needed for both street and performance applications.
