SCE Gaskets Exhaust Manifold

SCE Gaskets Exhaust Manifold Gaskets: Race-Proven Sealing Technology

When exhaust gases are escaping where they shouldn't, no amount of horsepower makes up for a failed seal. SCE Gaskets has built its reputation as a go-to source for performance engine sealing, and their exhaust manifold gaskets reflect the same engineering discipline that has made the brand a recognized leader in racing and high-performance applications. SCE brings two distinct exhaust manifold gasket product lines to the table — each engineered for a specific performance demand — so builders at every level can find the right seal for their application.

Pro Copper Exhaust Manifold Gaskets

SCE's Pro Copper series is among their most celebrated offerings in the exhaust manifold category. SCE Pro Copper Annealed exhaust gaskets are manufactured from reusable flat annealed copper and are designed to conform to rough or damaged flange surfaces, providing a tight, leak-proof seal even under demanding conditions. The soft copper material allows the gasket to flow into surface irregularities that would defeat a harder composite gasket — a major advantage on engines with aged or lightly damaged flanges. Pro Copper gaskets are available for a wide range of classic American V8 applications, including Small Block Chevy square-port, Big Block Chevy round-port, and Small Block Ford configurations, making them a natural choice for muscle car builds and nostalgia racing programs alike.

AccuSeal E Series Exhaust Gaskets

For builders who want performance-grade sealing without stepping up to pure copper, SCE's AccuSeal E Series delivers an excellent balance of durability and value. The AccuSeal E line uses a Kevlar® and graphite material combination that provides extreme heat resistance, strength, and resilience against blowout and burnout under exhaust manifold pressures and temperatures. The composite construction also offers good adaptability to seal header and manifold flange irregularities, and the gaskets can be easily trimmed for modified port applications. AccuSeal E exhaust gaskets are available for nearly 20 port styles in a variety of sizes, covering applications from the early 1950s through modern platforms — including oval-port Dodge small block Magnum, Big Block Ford FE, and many others.

Why Choose SCE for Exhaust Manifold Sealing?

SCE Gaskets — now part of the global Athena Group — combines decades of on-track development with advanced manufacturing processes, including CNC technology and dynamometer testing. Their innovations include embossed copper exhaust gaskets and proprietary gasket coatings that enhance sealing based on flange surface roughness and material expansion characteristics. Whether the goal is a weekend cruiser, a track-day build, or a full-tilt race engine, SCE's exhaust manifold gaskets are engineered to hold their seal where it counts.
