You don't want to heat the bolts themselves. Heat the radius arm around the threaded portion of the bolt hole. Heat expands metal. You want to expand the area around the bolt, not the bolt. The bolt will get really hot which is ok, but try to focus on the metal around the bolt.
If you just have a propane torch don't even bother with it. It won't get the arm hot enough. If it is an oxy-acetylene torch give it to it.
Heat in combination with a high quality impact gun will break it loose or break it off. One of those cheap guns with an advertised torque rating is not the tool to use. You will need a MAC, Snap On, IR, or similar gun.
I did have a bolt break on me a while back. It takes a real impact gun to break one of these bolts.
