You have to be INSANE to have long-tube headers on a big-block A-body Mopar!
Jim, just a word to the wise. You're going to want to clean the area up really good on that torsion bar where you vise gripped it. Dress it with a file and get it back as SMOOTH as possible. Any imperfections like that can lead to the formation of a crack, because they are very hard spring steel. That's why it's recommended you use a torsion bar tool to remove them. Make sure it's good, smooth and clean.
But man, you're gittin with it buddy! lol
