LucaSng A Pair SBC Oval Port Copper Header Exhaust Gasket Our Score: 79% - Satisfactory

Best gaskets you can get! My cylinder head was leaking and I had to buy a new one. I had two sets of these and they were both too big. Not knowing what else to do, I bought a set of the ones that were recommended by the mechanic and after installing them, they still leaked. I went back to the store and bought another set of these and they stopped the leak! If you're doing a header job on an oval port Chevy engine, these are the gaskets to use! They look great too!
