There's a reason why I would be going non-vtec rather than vtec
According to Bisi, the f22 head is the "BEST" flowing head Honda made. In addition, the f23 vtec has a unique exhaust port layout, so there's not a good header for it. Also, the cam selection is limited. The f22 head is Bisi's head of choice, so the cam selection is much better.
LSVtec were created because LS head didn't flow as well as Vtec heads. So I would be basically doing the same thing. When it comes to f-series, the non vtec head flows better (somebody correct me if I'm wrong).
