I am currently removing a 5.0 tuned port engine from an 87 trans am. It was over reeevvvveed and now knocks. I removed all the bolts from the tuned port runners and am missing something. The tubes seem to be stuck on the bottom. I do not see any more bolts. This seems to be the best site for 3rd gen. What am I missing ?

Well, if you have removed all the bolts from the runners including the two (one on each runner) that are mounted on the inner side of the runners. Then all that would be holding it would be the gaskets. Just tap with a mallet and they will come off. The two bolts I mentioned, (if you haven't already removed them) are located as follows.

Right runner = by the first tube.
Left runner = by the last tube (fun to get out)

Moved.
