Intake Manifold Gasket ?

I have used both. Either one is okay. I always throw away the cork or rubber front seals and use silicone along the front and rear edge, taking special care to get a good bead where the head / intake/ block come together. I used the Edelbrock on my 318, and just Tuesday night I replaced the gasket in my 408 and used Fel-pro. They are both quality seals. Feel confident using either.
