The general configurtation of the base gasket is the same, with the exception of the extra KIPS shaft, so you could probably use a newer gasket on a older bike, but couldn't go the other way. If you were going to use a newer cylinder on an older bike, you could use an aluminum epoxy, or have the crankcases welded to support the additional KIPS shaft, use a newer cylinder and head, and the KIPS actuation arm would have to be changed, the newer pin is smaller.
So by the time you've done all this, it may be cheaper to buy a newer motor slip it in your bike and be happy.
