Pulled the head. Block has several repaired cracks, and the head needs resurfacing. I think the combination is the reason for the loss of coolant/ overheating.
 
Any of these could be the culprit, but if you already know the head
needs to be milled, I'd start with that and a new gasket properly torqued
might be the cure. Good luck.

If your loosing water in the oil or elsewhere you could try a liquid glass, it work for a tractor i had, for many years
 
The block is not usable. one cylinder has a crack that goes from the exhaust valve into the cylinder(#3). If I can't find a usable motor the owner will probably part out the huckster.
 
Finding a crack free block is getting hard to do but they are still out there. The current issue of the Model A Times has an article showing the most common locations for cracks to occur to help you when you are looking at a possible replacement. There is also an article on the new block that is in development and will eliminate the frustration with locating a good core.
 
Thanks john. Until I pulled the head and cleaned and scraped everything I was hopeful. This block must have been overheated a bunch. Very little ridge in the cylinders, but the cracks are very noticable and felt easily with my thumb nail. A hard seat at each exhaust valve (#2, and #3), and a 1 pin repair at each crack next to the hard seat, tell me the rebuilder should have caught this, and probably did.
 
Mike, You'll need to ask him. I think dealing with health problems has something to do with it. I'm looking for a reasonablely priced replacement. Maybe I'll get lucky. So far no good leads have come my way.
