It's not really feasible for another reason. I mean it's doable, but you are going to put more effort and money into it then you are going to get out in hp or drivability. The head alone won't do the trick, you will need the ECU, harness, fuel system (most of yours would work though), as well as some other things. It's not just a simple swap and tune.
You can achieve good drivability, down low power, and more peak power by reworking your existing head, using a ported and polished TB (or a bigger one) and opening up your exhaust. The 2.2 motor is far from maxed out in stock trim.
