Chevy SBC 350 Round Port Copper Exhaust Gasket Set heat-treated to a maximum strengthThese Speedmaster exhaust gaskets are made from thick copper, and feature an embossed ridge around the exhaust port for a tight, leakproof seal. The copper gaskets help even out the flow between the head and header flange to minimize warping. Also, they'll conform to rough or irregular surfaces to maintain a positive seal, while keeping the header bolts tight.
