attach a lift to the head and see if you can pull it off. let the weight of the engine do some work for you

Is the engine out of the car? If so, I think biodude's idea is a pretty good one (although attaching the lift to the head might be a challenge).

If the engine's in the car it's going to be tough for the penetrating oil to really penetrate since the bolt is horizontal.

I'm not familiar with the head design on the EJ22 - any chance there's enough of the bolt shank exposed that you could put some bigass vice grips on there?

Id assume the block has to be out of the car

as far as attaching, use two outter most exhaust studs and two outter intake bolt holes, you can attach a chain or whatever to 4 points and that way you should be able to pull up on the head pretty evenly,

Yeah, that should work pretty well.

A little bit of weight pulling the block down, soaking in PB Blaster or whatever, and tapping on the exposed bolt shank is likely to do the trick. Remember you don't have to elevate the block, just get the bottom of the stand a fraction of an inch off the ground and all the weight will be on the corroded surfaces.

See where I'm going with this? If you've got the time, stretch this process out for a couple of days. If you can leave it hanging by the head while doing this then all the better. Otherwise I suppose you could try drilling out the remaining bolt shank at least down to the block.

You do have all the other bolts out, right? I've done that once or twice on a water pump. "Why won't this stupid thing come off!?! Wait... Oh.. whoops."

I agree with wrencher86... there isn't much that cycles of heat and penetrating oil can't take care of! Good luck!
