Well, I can answer this one. http://65ss.com/index.php?m=20040605
If you look at my June 5th post, I show the differences in BB and SB mounts. The ONLY difference is a small recess in the mounts. If I would have known this, I would have saved about $100. If you big block clears the mounts, then you're fine. They are the same height. If you click the thumbnails, it will enlarge the pictures for you.
