Worth pointing out that this isnt HG related failure, from the sounds of it water is just leaking out of the water port on the back, i.e just a water leak? Which means A. its should be fairly easy to weld the crack up and B. That the HG is fine.
Also, a pressure test at a machine shop usually only tests the pressure of the valves/cylinder area, not the water and oil ways, so this wouldnt have shown up.
Knowing how much that water port/pipe sticks out at the back of the head I would assume its been dropped or caught which has cracked it. You'd be downright unlucky to have that crack under normal conditions.
