I was reading that a B204 - T5 head flows better than a B202 and that a T7 head is even more impressive. I have seen pictures and a writeup that shows a T5 head fits with minor work on the chain cavity side. What about a T7? I read about all these sludged T7s and hope that I can get my hands on a T7 head cheaply. These appear to be the same, as far as bolt up, as a T5. What will I need to use for an intake? I am starting with a 2.1L intake and was going to match the ports. Anyone looked at this? The EPC is not too clear to me. Do I need a 2.0l or will a 2.3L work just as well?
