A copper gasket is less likely to seal something like that then a Fel Pro composite. But a question was the Block decked? it doesn't look like it to me. If you had the Block decked .005 to .007" it would flush up those sleeves. Granted thats a PITA but it would take care of it. As to the leak are you talking about the little chip looking hole? If it were me I would first find out if that reaches the water jacket.
Also you do not put any lube on the stud threads it will screw up your torque numbers clean and dry with a generous coating of Pematex II on the thread that go into the Block and screw the studs in figure tight (should run up to the center section) then allow the sealer to set up for 24hrs. Spray a Fel Pro gasket with copper Indian Head sealer and then Torque to spec. After about 10 hours run time and after the engine reaches room temp after a run retorque.
