That's been my experience too. What it really depends on is the relationship between the smallest cog and the hub's locknut. If you have enough space so that the chain will shift onto the smallest cog and not rub the chainstay, you're good. If it does, you'll have to put a washer or a spacer or something under the drive side locknut. Depending on how much you have to add, you may have to take a spacer out of the non-drive side. Obviously, the more that you do, the more likely you'll have to adjust the dish.
If you do find that you have to adjust the dish, make sure that you have a supply of new nipples before you start. On a wheel that old some of the nipples are going to be stubborn and will round off when you try to adjust them.
