Things are pretty tight in an A-body. Even with a small block. But based of all of the information from this thread, I think this will be my plan of attack for my break.
1) Attempt to remove header and dimple. 2) If 1) fails, shim engine. 3) If 2) fails add resonators out back.
Taking a look at the engine bay, I feel more confident now.
Quick question. Is it worth it to replace my biscuits? The passenger side looks smooshed, kinda? If I do, should I go rubber, solid steel, or poly locks?
