Answer
Hi Dick:
First the black spots are water mixed with rich exhaust smoke. Having a little water coming from the exhaust is OK. I have to assume that you replaced the gaskets when you had the heads resurfaced. If not, this should have been done as well. Also, if you are only seeing a little antifreeze, that could indicate the heads have not swelled around the gasket yet. I suggest you give her 50 miles or so to heat the engine to a point where the heat will seal the head gaskets. This should solve your problem.
