If either all the water was not removed or the engine not properly winterized with antifreeze and it was subjected to freezing temperatures, there is a chance of freeze damage to the block. Reading your post it struck me as a possibility.

If it were me I'd want to know the water jacket was intact before moving forward on a rebuild. If the assembled block and head will not hold a modest pressure you know the cooling system has suffered a mortal crack. The manifold can be tested separately which I recommend also.
