One word of caution -- if you have a tire on that rim, let the air out and remove the valve core from the stem before applying much heat that can transmit through the rims to the air in the tire.
Where they're not threaded you're ahead of the game.
What the heat does is break up and crumble the corrosion between the bolt and the hole. I usually give it a good heating all over, both the bolts and the surrounding iron and let that cool. If it needs more, I'll give it another shot, focusing on the bolt. If you've got the heads on the other side, put heat to the head until it's mostly red, and let that cool. While it's still good and hot but not necessarily sizzling, give a shot of whatever your favorite penetrating lubricant may be, wherever you can get it (around the bolt head, between the pats, anyplace you can get it and keep applying it. As it cools you can see the stuff draw in to the small spaces opening up as the corrosion crumbles. Give the surrounding area more heat, starting well away from the bolt if it needs a third shot, to expand the outer part, then go for it while the outer part is still hot.
If you have an O/A set up, you know more about how to heat with that than I do. Myself, I use just the home-owner handheld torch with Mapp gas (hotter, faster) instead of propane.
For driving them out, another old bolt (you'll bung up the threads at the end) the same size or one size down is useful. If you have a good drift of a size that will work that's preferable. What I'm saying is you may still need to wallop these things to get them started and I have a box full of bent and chipped taper punches as testament to what not to use.
In your particular situation, it may also be useful, in addition to any heat, to try tapping a wedge, pry bar or chisel between the parts to be separated, if you can find a place to fit one that will let you swing a hammer or get good prying leverage. That might pop it loose enough to drive them out more easily.
Patience and persistence in the right balance is key -- swearing or other verbal lubrication is allowed and can be therapeutic. Keep the hammer rule always in mind -- Hit with progressively bigger hammers until you break something, then back down one size. ;8^)

Today's Featured Article - Old Time Threshing - by Anthony West. A lovely harvest evening late September 1947, I was a school boy, like all school boys I loved harvest time. The golden corn ripens well and early, the stoking, stacking,.... the drawing in with the tractors and trailers and a few buck rakes thrown in, and possibly a heavy horse. It would be a great day for the collies and the terrier dogs, rats and mice would be at the bottom of the stacks so the dogs, would have a busy time hunting and killing, all the corn was gathered and ricked in what we c
