I've been there as well. Never did get the breaker bar and starter motor
trick to work for me either. I ended up filling a tank of air (It was
about 175 psi) and using a friend's impact wrench. I only got about three
seconds of use from the tank, but it was enough to break it free.
Going back on was much easier using my huge torque wrench. While you're in
there I'd replace the timing chain and tensioner as well.
