You wouldnt know the name of at least one break free product would you?
I wouldn't put too much faith in those if I were you. Anything that's seized bad enough to require lubricant has usually also seized so tight that lubricants won't penetrate very well. It won't hurt though, so make sure you give the fork a blast from below too. It sounds like you haven't got aheadset, so that's where your stripped bolt is anchored anyway.

There are two common anti-seize products available, one graphite-based and one that consists of copper flakes suspended in grease. These work better than pure grease because even if the grease dries out it leaves particles behind that helps lubricate the threads. I prefer the graphite-based stuff, with that I don't have to worry about any compatibility issues between different metals.
Extractors are sort of tricky to work with, and since you're already committed to destroying the bolt there's another way available. Ask around for someone who has an arc welder (stick will do). Put a (large) nut on top of your stripped allen head, and weld a large bead through the center of it to lock the nut to the stripped allen head. As soon as it has cooled you can then use a wrench to get it loose. Remember that you don't have to unscrew the bolt the whole way. Once you've got the bolt to lift a couple of mm you can tap it down with a hammer and that will usually retract the wedge enough to let you remove the stem.
