Exhaust Gaskets SBC 1-7/16 Round Port

The Exhaust Gaskets SBC 1-7/16 Round Port are precision-engineered header gaskets designed specifically for Small Block Chevy engines running round-port manifold configurations. As a mechanic who has rebuilt countless SBC platforms, you know that exhaust leaks at the manifold-to-head interface are a common frustration—they waste horsepower, create noise, and invite carbon buildup that compounds future problems. These gaskets solve that problem by sealing the critical junction where hot exhaust gases exit the cylinder head, ensuring every combustion stroke's energy flows through your exhaust system rather than bleeding away.

REMFLEX Exhaust Gaskets' Exhaust Gaskets SBC 1-7/16 Round Port feature a graphite composition that handles extreme thermal cycling far better than traditional compressed asbestos or soft-steel designs. The 1-7/16 inch (1.437") round port specification matches OEM and popular aftermarket round-port heads, ensuring a tight fit without modification or adapter rings. Graphite's superior heat resistance and conformability mean these gaskets maintain their seal across repeated heat-soak cycles—critical when you're pushing cylinder head temperatures to 350–400°F under sustained load. The pair configuration lets you address both sides of your engine simultaneously, eliminating the likelihood of one gasket outlasting the other and creating asymmetrical exhaust leaks.

These gaskets are ideal for street SBCs, mild to moderate performance builds, and restoration projects where authenticity and reliability matter equally. Whether you're building a 350 for a truck, refreshing a classic Corvette small block, or upgrading a Camaro powertrain, the Exhaust Gaskets SBC 1-7/16 Round Port work with both stock and ported heads as long as the round-port design is maintained. Installation is straightforward—simply lay the graphite gaskets in place before bolting manifolds to the head—and they require no special sealant or re-torquing rituals once properly seated. For anyone serious about eliminating exhaust leaks and maintaining peak scavenging efficiency, these gaskets deliver lasting performance at an accessible price point.
