Oil Filter Plate

I have a friend who's just wont stop leaking. We have replaced the gasket twice and it still leaks. The engine is a fresh build with maybe 10 miles on it now. The block was tanked prior to the build. Is it possible the plate is bent in some way? Has anyone tried double gasket's with any success?

I am not talking about a 90* adapter, just the factory metal plate.

Thanks
