Spray something like a good penetrating oil on them and brush them. You can even use a little bit of exhaust-rated anti-seize if you like. Definitely replace the nuts. If you really want to replace them, you can try a bunch of things... Really soak them with penetrating oil, tap with hammer, let sit for a bit... Inflict heat... However you prefer. Then double nut and see if they budge... I tried... As soon as I felt like it may not end well, I gave up! I REALLY don't want to be extracting broken studs on an otherwise rideable bike...

But you may luck out! I still think about it sometimes, but I always force myself to think of the downside too. Then I stop thinking about it.
