I can tell you it won't fit. Been there, done that. Because of the shape of the manifold, it hits the head where the manifold curls under. I tried removing some of the manifold material, but too much material needed to be removed for my comfort. I got a header flange to act as a spacer. You'll have to use 2 gaskets, 1 between the flange and the head and 1 between the manifold and the flange. There's probably a better way, but that's how I solved it. I did speak with a tech from Edelbrock, but they couldn't offer a solution.
