    As a high school kid, I worked at a Mobil station in Allen Park, a suburb of Detroit. One of the owners had a '53 Hudson Hornet with the factory aluminum head. Our mechanic prepped the head for removal to do the valves. There was no prying, prodding or cussing that could make that head release from the block. Turns out, that was a common aluminum head issue. The mechanic suggested reinstalling the plugs and plug wires, and starting the engine. KABOOM, off came the head, and copious amounts of coolant. The four remaining loosely installed bolts kept the head from orbit. We laughed for a long while!

    Dissimilar metals do have a tendency to 'corrode' together after some time. Old coolant with some acidity will make a fairly good electrolyte to compound the issue. A copper head gasket would probably also contribute to the issue.
    Aluminum wheels stick to steel hubs all the time. Wet, salty environments seem to make it worse.
    The large displacement Hudson 6 with the Twin-H power was the terror of the track in the early '50's.

    Chrysler tried composite head gaskets on the Slant 6 way back when. The same thing happened from just running a few hours on the dyno. We would loosen all the head bolts except for a couple, hook the chain hoist to the head, and then crank on the hoist until the head popped free.
