You need a small gap (2 to 4 mils) between the pieces to be able to make a good joint easily, so the solder will flow smoothly into the joint. Just machine a 3 mil step around the edge of the block extending half way across the flat.
(and no, you don't have to get the solder completely across the flat to get a good seal,though it does help from a thermal transfer standpoint between the block and top)
You could also do it without machining in the step. You can get solder paste and apply to the mating surfaces. If properly prepped, then you simply heat the block/top together and the paste liquifies to form the joint. (although this really works best with a silver/copper brazing paste)
