Thought I would update this... 3.5 hours to get it out, I am getting good at this..
Engine went to the builder, and we are going to replace pretty much everything except the block. This engine was rebuilt once using some of the cheapest parts that can be found. They used generic fit all cast pistons and reused a lot of old parts that had wear on them. By not replacing all the stuff, it looks like it caused some of the issues I have been trying to figure out for 4 years. Most notably, the impressive LACK of power. The last drive my bird took was out of my garage, to the street, the backed into my garage. On the last start, I noticed it was knocking until it hit full idle. So, great time to get this rebuild done. For you Indiana guys, I have Scott Gunderman doing the rebuild. He has extensive Pontiac knowledge and about 40 years of experience.

We went through the parts that came out, and wow were they worn. I included the worst in this reply. If you have any other interest in pile of junk I have from the guts, let me know, I'll post more pictures.
