But back to the truck, Thanks for the offer on the head I'll get back to you. Because I did some searching last night may have found a NOS head according to the old Maple Leaf master parts book which covers 1938-1951 the one I've found should interchange OK. I had forgotten to bring the head casting numbers to confirm things though. This morning I'll get my casting numbers and engine numbers and give them a call.
I was surprised by how clean the inside of the engine was, wonder if part of that is the positive crankcase ventilation and the oil bath breather for the crank case.
The gunk on the tops of the intake valves and the gunk in the intake ports does say that oil leakage around the valve stems was a problem for a long time.

Phil..
I would be tempted to fire that head in the forge and weld up those cracks and re machine the seat..(At least get the machine shop to do it)
That crack does not go through to the water jacket and for the miles that you would put on the truck would last forever,..
With 95 PSI compression,you are close to good to go..
