Perhaps it is time for a 3rd opinion! I think a third opinion might be a good idea. If you can see that one of the freeze plugs is bent, chances are pretty good that it's leaking. Those plugs are meant to fit pretty tightly in there (remember that the cooling system is under about 16 psi at operating temperature) and if they're installed crooked or bent, they will leak. > If it is cracked it really is not noticable as the > second mechanic swears that it is not cracked and > that the coolant is seeping thru pores in the > block...

Now, I realize that I don't get out much and all, but I'd sure like to see a good, scientific explanation of how water can seep through "pores" in a cast iron block. ;o) Cracks, yes, but pores? Um . . . and most of those sealants are meant only as a temporary stop-gap measure, and not a permanent fix. In fact, "stop-leak" can cause more problems than it fixes, by blocking up heater valves or some of the smaller water passages in the block. Hang in there -- the 413 is an incredibly durable engine, and finding one with a cracked block is pretty rare. This may turn out to be a relatively simple fix. Good luck!
