PRC 2.5's or AFR 205's with F13 I really can't decide which heads to go with, It's a daily street driven car and I would like to get 450whp (6spd/10bolt). I have all supporting mods(LS6 intake not LSX). Would either of these heads need to be milled for what i want and what size valves would work best?

Yep, that's what I'm doing on my car too.

Since money was not mentioned, although a valid concern, I to am curious what would be a nicer choice. PRC 2.5 with port matched FAST setup, or AFR 205 with port matched FAST setup, both using the same cam? What would you do and why?

I'll look into a 12bolt when my little 10bolt breaks. Car will rarely see the track. Now i'm starting to lean towards a NX setup instead of heads....can't make up my mind

get the heads, then get the nitrous
lol... do a 75-100 shot when needed.. dont plan on hooking anywhere and not breaking tho.. honestly id buy the 12bolt instead of the heads, and then get u some nitrous.
