Yes, stock or modified 930 cams will have overlap.
I do not know if there is a point in the engine's rotating mass cycle that all six exhaust valves are closed but that's the point you want your crank to rest when checking for leaks. It would be ok if a cylinder or two's valves were in overlap provided it's the intake valve that's open.
