Alright its time to buy the heads and i dont know which ones to get. The 3 that I am considering are the Trick Flow twisted wedge, Edelbrock performer, and AFR 165's. I know that the AFR's are good but cost is a big factor for me. Are they worth the extra money? Or do either of these other heads work/flow just as well? I am puting the Trick Flow Street Heat Intake, and 70mm TB on there. Thanks for the help.
