I went over to my friend's house and we were going to pull the motor out of his Camaro when we ran into an issue. We have no idea how to get the headers off of the heads. Two of the primary tubes on both sides have a bolt next to them that we have no idea how to remove. The tubes leave the heads and immediately bend back so they are right next to the bolt and almost directly over the bolts. There are two like this on each side so I can't remove all but one bolt and turn the heads because there are two on each side. Any advice to remove these would be greatly appricated. They are internal allen heads.
