I was wondering what heads anyone would suggest for a single turbo'd 468? Right now I have a set of brodix bb2 plus cnc'd heads with 320cc intake runners and 2.25 intake and 1.88 exhaust, but I want to make sure these are large enough and are not going to cork things up. I have a pt-106 turbo and am looking for 1800-2000hp. I ran these heads previously with a F1-R procharger and made around 1100hp. Any suggestions would be great
