    Do you run AVCS?

    If you are running AVCS on your block, the USDM EJ205 heads will not really work. You'd need to plug the oil lines and disable the AVCS in your ECU to run EJ205 heads. If you are not running AVCS, then you could go to the EJ205 heads. EJ205 cams are a little milder than the EJ257 cams and much milder than the EJ207 cams. However, EJ205 heads also flow more than either EJ207 and EJ257 heads, and with some valvework and aggressive cams have by far the most capability for flow.

    So. If you are going to build a set of heads, and you're not concerned with AVCS, then I would build the EJ205 heads. If you are running AVCS, the EJ205 heads won't work anyway.
