I dont know much about the heads specifically. But I would imagine the reason that your thinking of going over to them is better flow/more performance. Anytime your increasing airflow you need to compensate for the extra air with more fuel. If you dont you risk of running lean and doing damage to your car. So you need to either use some sort of engine managment that allows you to mess with the fuel curve or you need to get your ecu reflashed for your mods. If you plan on not modding too much then a reflash would probably be your best bet. But if your going to be constantly tuning and modifying then an investment in a good afc or some sort of engine managment would be a good idea imo.
