HSD, head stud developments.. You wont need a crazy port job to crack 11s with forced induction, just a good flowing open chamber should do it.

I see you're in Queensland, 190cfm with a 9 port is not out of reach from most decent head porters. Anything over 200cfm is going to cost a fair bit but 190 in a 9 port should not be too hard to achieve.

Would have to say the head stud development guys know their stuff, I live in QLD and got them to do my head (12 port) . Cant believe how much louder the whole engine is with a good flowing head compared to stock.
