So i found a difference in the LQ9 and LS! blocks that i never read about on the forums and thought i would share. Upon installing all my bolts for my F Body oil pan, ended up with extra bolt. Had to drill and tap hole for screw which was a bit scary with the bottom end built and ready to close up. FYI

Which one is not there, or what side of the pan. Funny, I do not remember missing any pan bolts on mine.

My 1999 LS1 block was also "missing" one threaded hole in the block. The factory pan and gasket would accommodate a bolt here. I drilled and taped the block for it.
