Well, I changed up the H1/title/meta tags while I was suffering this weird problem with the penalty and wrong pages showing up, etc.
10 days later, the penalty went away.
Then another 12 days later it came back, even worse than before.
So I can't really say whether or not changing that stuff made a difference.
