[DeTomaso] ideas as to removing aluminum head

[jderyke at aol.com]

You can try a trick I used to use on flathead Fords with aluminum heads, which had 24 studs and were notoriously difficult to remove. The antifreezes in those days didn't always stop aluminum corrosion. 

Add a couple of nuts a few threads back on each head, add spark plugs, then hook up the starter. The 120-psi or so of compression pressure should lift one or both heads & the nuts will keep them from falling off. Keep pulsing the starter until both heads lift. 

Someone probably used paint on the gaskets to increase the sealing. Paint works but makes things difficult for the next guy working on the engine. And if the PO used epoxy on the studs in the block, they won't come loose unless you heat up the engine somehow to soften the adhesive. 
Good luck- J DeRyke

  Need some advice as to removal of the aluminum heads on a Fontana
  block. It looks like it has a Fel Pro head gasket.

  I have all the valve train off, and the nuts on the studs. The heads
  are firmly on. I have pride on them and took a dead blow plastic hammer
  to them.

  Nothing has worked and I am afraid to really pry on them, as to not
  damage the block or heads.

  I would appreciate any ideas as to breaking the suctions.
