Right angle oil filter adapter question; gaskets?

I bought one used, and the gaskets gaskets were in the gasket set I bought seperate. The cork one doesn't contact both the block and adapter, the block surface in the center is too far in, which led to my question. If you put a straight edge across the outer gasket surface with the outer gasket in place, plus the inner cork gasket against the block, there is still about .100 space too much for the cork to touch the block and adapter.
