I agree with "JSeery"; avoid removing the heads and fooling around with the studs if at all possible. Getting the nuts off without breaking any studs is just the beginning of your problems. You can have every nut off and in a can 50 feet from the car and the heads usually still won't move. If you have the time, browse around the web for pictures of fixtures that were made for this very purpose. Most of them resemble medieval torture devices and can cause almost as much pain. That will give you a taste of what you're in for.
