I am curious, is it best to heat the bolt head itself or around the
bolt? Will Heating the bolt heat make it more prone to snapping off?

It seems heating a bolt would make it expand, making it tighter?

By the way on all the other bolts I removed there was no rust.

I was tought that it's the differential expansion across the bolt/block
interface which cracks the rust. ("Block" being the thing the bolt's
screwed into.")
