I was a hack sawer for one of the early boss head projects . It was absolutelly welded with a stick welder, but the owner claimed you had to use new castings. Cast iron is very porus and used heads were full of contaminants.
We cut the two end cylinders off one head, and cut the other head in half. The pieces were bolted to a block and John stick welded 3 sides. Remove it from the block and weld the 4th side.
