Exhaust Gasket Set SBC w/Oval Ports

The Exhaust Gasket Set SBC w/Oval Ports from REMFLEX EXHAUST GASKETS is a precision-engineered pair of header gaskets engineered specifically for Small Block Chevy engines equipped with oval-port cylinder heads. As a seasoned mechanic, you know that header gasket failure is one of the most common causes of exhaust leaks, lost horsepower, and diagnostic headaches on the street and strip. This graphite gasket set eliminates that frustration by providing a reliable, reusable seal that outlasts traditional composite gaskets and resists the thermal cycling that destroys inferior materials.

REMFLEX gaskets are manufactured from a proprietary graphite composite that conforms precisely to the 1.500 x 1.750 inch oval port geometry of your SBC cylinder head and manifold mating surfaces. Unlike traditional compressed asbestos or coated steel gaskets that degrade under sustained heat, graphite gaskets remain stable across repeated temperature spikes, maintaining port alignment and preventing exhaust blowby that robs power and creates troublesome vacuum leaks. The matched-pair design ensures symmetrical sealing on both banks, critical for balanced scavenging and consistent air-fuel ratio across cylinders.

This exhaust gasket set is the go-to choice for any SBC modification project—whether you're running a stock 350, a carbureted stroker, or a fuel-injected crate engine with modern cylinder head castings. Installation is straightforward: no special tools or techniques required. Simply remove your old gaskets, clean the mating surfaces with a brass brush and solvent, and lay down the new set before torquing your headers or manifolds to specification. REMFLEX gaskets are reusable across multiple header removals, making them economical for builders, restorers, and performance shops that demand reliability without compromise.
