Any gasket can create a seal, but a good gasket can do it with less clamping force, and for a longer period of time. Edelbrock's gaskets are not only manufactured from extremely high quality materials, but they're also designed specifically to fit our intakes and cylinder heads, so there's no chance that our gaskets will interfere with the operation of either component. These gaskets also work with most stock cylinder heads and intakes, aluminum or cast-iron, as well as other aftermarket components. Top quality Edelbrock gaskets ensure a perfect seal every time.
