As an update, I pulled the engine apart (mostly) One bearing (on piston #3) really spun. This must have been for a while, because there is no one it happened within only a few miles. Also popped out one of the pistons to check the rings. On #8 the top ring was actually broke.
I might not even need the heads cam and intake if I just do a basic rebuild. Itll feel like I have a whole new engine in it
