Buick 231 V6 Pro Copper Exhaust Gaskets

The SCE Gaskets Buick 231 V6 Pro Copper Exhaust Gaskets (Part 4472) are precision-engineered header and manifold gaskets designed for reliable sealing on Stage 1 cylinder heads. Constructed from pro-grade copper, these gaskets deliver superior heat resistance and durability where exhaust systems experience extreme temperature cycling. Supplied as a pair with 1.075 x 1.500-inch stock port dimensions, they provide OEM-quality sealing without the premium price.

Copper gasket material is the preferred choice for high-temperature exhaust applications because it withstands repeated thermal stress better than conventional composite gaskets. The 1.075 x 1.500-inch port specification matches the flow characteristics of Stage 1 Buick V6 heads, ensuring proper gas seal without inducing turbulence or backpressure issues. This gasket pair handles both street and performance driving conditions without degradation, maintaining a tight seal across extended heat cycles that would degrade lesser materials.

Buick V6 engine builders and restorers rely on SCE exhaust gaskets when assembling or refreshing high-mileage engines or modified builds. Whether you're rebuilding a stock 231-cubic-inch engine or upgrading with performance heads, these copper gaskets provide the leak-free seal needed to prevent exhaust bypass and maintain proper scavenging. Installation is straightforward on most Buick V6 applications with Stage 1 head configurations.

SCE Gaskets manufactures gasket solutions for serious engine builders and performance shops. These pro copper gaskets reflect that builder-focused heritage—they're specified by professionals because they deliver consistent, repeatable sealing without the guesswork of lower-grade alternatives.
