This video explains the major issue that was discovered right at the tail end of the restoration process on the day we were going to start the tractor,

It looks as though the head bolt holes have water in them which means the holes are connected to the water jacket. If that is the case, the head bolts need to be sealed when they are installed. Otherwise, water will infiltrate via the head bolt hole.

Did you put pipe dope around head bolt threads? water coming up bolts from water jackets.

Use copper paint on the head gasit and can used for 2 time. I do it all time 1943 farmaĺl

This might be a stupid question, but did you use a straightedge to check both the top of the block as well as the head to make sure they were straight? If the head is warped as you suspect, it would possibly show up with this test. I would suspect the head as well since the water was in all of the cylinders. If you have a good machine shop nearby they may be able to plane the head. They should also be able to deck the block to ensure a really good mating surface.

Good luck. Maybe have the head checked out.
