Putting my throttle body back together, the main shaft return springs seems to be weak so I wrapped the spring one more time, it was very tight, then the one of the pieces of wire on the springs wouldn't let the main shaft seat all the way, I took a small "j" hook and remove the spring from the catch, it seems to be better now on to the butterflies, there is no DAG on them nor was there before I took them out. The butterflies do go in and seat at an angle correct?

Yes, they seat at an angle.
Let them seat closed first with screws slightly loose. Then tighten screws with the butterflies fully seated.
Don’t forget the red Loctite on the screws.
