Hi Mike
As I reported earlier, I put two well corroded head / barrel assemblies in diesel for two months and then, having made a significant jacking rig then both heads came off reasonably easily. I do have a 250 amp arc welder and could try Doug’s method, so please let us know how you get on.
Whatever method you use to break or reduce the adhesion between the studs and the head, the volume of debris still exists, rather like removing nuts from studs that have been fitted with Loctite. I am interested to know how you will restrain the components after the “treatment” in order to push the head off evenly.
I would hardly expect it will drop off.
