[what's that?]

I know that AFR's are good stuff, but that does not tell me what roush is using, or if Roush CNC heads are their old GT40's.

I'm asking because I can either buy AFR's that I know flow well and are very consistent because they are CNC'd, or I can try to buy a head that I think has what it takes, and if it does not, I'll have to buy new heads or spend lots of money to get them ported by a pro.

I just looked at TEA and their twisted wedge 185 looks interesting and the 205 looks like more than I need, but the price is pretty good.
