I don't think a heat gun would make much difference at the joint. Maybe a propane torch at the studs, with your favorite penetrating oil.
A search here for Head Removal should give you a lot of tips.

I'm wondering where the sticking points actually are. Surely the head gasket keeps the head and block from fusing together with rust? Is it around the studs where they go through the head that the fusing occurs? If so I think heat and penetrating oil on the studs would indeed be a good start, before the hoist.
I have a hoist leveller, in which case would the angle iron in your picture be necessary...perhaps for load sharing between the bolts?
