To PP or not

To PP or not
ok, I'm fishing for some help/info. Got 2 new 13b hsgs and want to upgrade my SCCA racer to a more competitive car. For a PP I was wondering what size hole everyone is using for the id of the added in sleeve. I know fuel and exhaust all have a bearing on the end result power wise, I just would like to do this once and get some VERY good results. I know Racing Beat does a threaded in sleeve with the proper porting but have no idea if they leave the port round or square at the chamber end. I'm thinking about 2" id tubing with a squared off port, very much like the 12A PP factory housing, only a bit bigger. Anyone with a strong, non-turbo 13b PP willing to share some port sizes, shapes etc.? This will run about 5500-9800 rpm and I don't care about lack of pull below 5500 rpm.
Thanks in advance
