Are you saying you want to change out the whole neck for one with a matching headstock? Why would you want to do that? Not all necks are made the same so it wouldn't be much of a "plug & play" scenario. You would need to get the guitar re-setup for perfection. If you really want I'm sure you can get aftermarket necks (not original Ibanez) but I discourage it. Probably can get a nice FX with the moolah.
