as they checked out for warpage.
Was there any water in  the oil ??? like I mentioned before I found
two core engines that I rebuilt leaked water into the oil do to
cracks from freeze ups, these cracks are usually found in the center
housing.
  Was there any evidence where combustion could have leaked into the
water or where coolant leaked out???

Ken, I found no evidence of water in the oil.  I also have not found where the original leak was coming from.  I have not had time to pressure check the radiator, but it is a throw-away because I can see the stop leak stuck in the core passage inlets.  The stop leak may have also fixed the leak.  It is pretty clear that the majority of the coolant came out through the pressure cap.  This was a case of me trying to fix a small (probably insignificant leak) and I caused the big one (with my brilliant low pressure cap idea)
 
No way to tell if combustion gasses were getting into the coolant, and all the inner o-rings (Teflon from Tracy) melted.
 
I will give that center housing a better look, and perhaps try to test it if I can think of a way.
