NOW I gotcha. Although I don't have a photo handy of the stamped steel valve cover I DO know that the adapters work with them. When the adapters were designed we were careful to cut the outer edge to exactly fit the gasket so the "lip" on the outer edge of the stamped valve cover would not hang up and prevent a good seal. The lip of the stamped cover actually fits over the edge of the adapter

When we tested the stamped valve covers the pair we got our hands on were repros from Tony Branda. Strangely enough, the bolt holes on the cast covers from Ford Motorsports and Tony Branda we tried fit an FE motor exactly but the two pairs of stamped steel covers had two bolt holes slightly misaligned so that the holes had to be slightly elongated to fit the FE head. We therefore used the cast covers to locate the mounting studs on the adapter figuring it would be easier to elongate holes in a stamped steel cover than a cast cover. Even when the holes were elongated the washer under the valve cover bolt covered the elongated hole nicely.
