    I’ve dealt with this before and it is aggravating to say the least. Yes, remove the cylinder/ head assembly and try a wood dowel from inside the bore to tap the head off. If you can get a little movement, then work it in and out going from one bore to the other. The problem is corrosion around the head studs has locked the heads in place. Usually whatever penetrating oil you use won’t get past the corrosion until you get a little movement. Heads are scarce, so take your time and work carefully.
