When I installed my shorty headers, the dipstick tube got bent pretty bad. I can't get it back to the way it was so I will be buying a new one. Where did you guys bolt the bracket to after you installed your headers?
the bolt you loosen up to put that tube bracket behind is in the middle and probably wouldn't do anything if you loosened the bolt. You really don't have any other choice. If you're worried about it, you could always loosen all of them and then torque them all back down - I can't remember if there's a sequence to header bolts or not.
