OP,

The studs in your head seem to have a close fit to their associated stud holes in the head. Attempting to get the head off by prying on any edge will just jamb the head with the studs and you won't get anywhere. You need to find a way to get the studs out and the head will likely just lift off. Your idea of thin jam nuts might be a good solution.

My suggestion would be to pull the engine, put it on an engine stand and the job will become much easier. When you do get it apart consider buying some broached ARP studs for the new engine so you can easily install and remove the studs with an allen wrench.
