SBF Copper Exhaust Gaskets

The SBF Copper Exhaust Gaskets from SCE Gaskets are precision-engineered header and manifold seals designed specifically for Small Block Ford engines running aftermarket SVO cylinder heads. If you're building a serious performance engine or restoring a classic SBF power plant, a quality exhaust gasket is non-negotiable—it seals the critical junction between your header or manifold and the cylinder head, preventing exhaust leaks that rob horsepower and increase underhood temperatures. This pair of copper gaskets handles the thermal cycling and pressure cycles that come with high-performance driving or street use.

Copper is the gold standard for exhaust gasket material in the hot rod and professional racing community because it offers superior thermal conductivity, excellent conformability, and resilience across repeated heat cycles. The 1.750 round port design matches the port geometry of SVO cylinder heads, ensuring a perfect seal without compression loss or blow-by around the edges. Unlike cheaper composite gaskets that crush and lose their seal after a few heat cycles, copper gaskets maintain their integrity through multiple engine starts, sustained wide-open throttle runs, and the temperature swings of street and strip duty. The gasket thickness and material composition are optimized to compress evenly and create a metal-to-metal seal that won't degrade under sustained exhaust heat.

This pair fits Small Block Ford engines equipped with SVO heads—a popular choice among engine builders pursuing higher flowing, better-breathing cylinder heads for street performance and competition builds. Installation is straightforward: position each gasket on the head before bolting down your header or manifold, torque to spec, and you're done. Whether you're freshening a tired 302, building a 347 stroker, or assembling a 363 cubic-inch combination, SBF Copper Exhaust Gaskets provide the reliability and thermal performance that serious mechanics and engine builders trust for repeatable, leak-free results.
