If you did have to dimple them more it wouldn't be much unless the flanges are warped more than I'm thinking and they had to remove a lot of material. I haven't seen yours of course but I'd guess it would be less than 1/16" but you could also use a thicker gasket. I think they make thicker ones like they do for head gaskets.
