During the cam break-in, I got about 10 minutes in at 3200 rpm and a belt broke. So the next day I got a new belt and gave it 20 more minutes. I thought no big deal, but it's my first so I could be wrong.

Ok so you broke in the cam with a heavy spring I assume since you didn't have to change them after. It could be a cam issue but without have a dial gauge to check lift its hard to tell from here obviously. I would take out a couple of pushrods from another cylinder if you don't have spares and install them in number 8. Adjust the valves on that cylinder using eoic method and check lift with a dial gauge. If it's not the same as others you have a cam going flat. I'd also redo the lash on the other valves to be safe.
As for the metal bits you'll have running through the engine well that's a problem I'd look at after adressing this issue and considering what you can live with. You could change oil and filter a couple times and hope for the best or start over. But if the cam is going flat you're starting over for sure anyhow
