From what I've seen on YouTube, Commodore motherboards are notorious for using really cheap IC sockets that only make contact on one side of the pin. Unseating and reseating a chip from one of these can make things worse, not better.

If you fit turned-pin replacements, it might be worth stacking an extra socket into each one just in case; it's a much messier job to remove one of these from a double-sided board if you damage it.
