They'll all work. Slight differences between some years, but every DOHC carb will work for you.
If you are getting new carbs anyway, you might want to look into some "good" carbs, as a lot of people have a poor opinion of the stock CV carbs.
Stockers are essentially good for every day riding, but if you want a high performance ride you should look into mikuni's. That said, you'll likely need to spend someone in the neighbourhood of $700-$900 for them, so that might be more than you spent on the whole bike.
Stock CV carbs can be found for much cheaper.
