Oil leak from between head and block

I´ve got a minor oil leak on the engine and haven´t been able to locate where it comes from, today I took a couple of pics of the area it´s leaking from.
This is what I found......:cheers:
....not!!!!
Any one got an easy fix for this?
The block has been square decked and the heads were supposed to been milled to straight surface. I´m using a steelshim head gasket, would an added copper gasket fix this leak?
