Had the same problem on the first assembly of my engine (527" Shelby alum. block, Keith Craft Stage 3 ported Edelbrock alum. heads). Changed head gaskets....same problem. Finally milled the surface of the heads....only took a slight cut, maybe .010". Put it back together and all has been good. Apparently the heads were not absolutely flat from Edelbrock.
