The raised mounting area is for a "drag" application, can you return it and get a non-drag intake? It seems to me they sell the majority of their performers without the wedge cut in the manifold. I had a "Blue thunder" Holman Moody style intake with the same rake, I fixed the problem by running a wedge spacer, then a 1" phenolic spacer, that was before they offered a non wedge model.
