well im looking to get a set of heads that will put me around 450rwhp with an A4 just kind of wondering if there are any CNC'd stock casting that can do that. don't want to really pay for afr or TF's if i don't have to. what would PRC5.3L stage 2.5's support for power. just found a set fairly cheap. it is a 383 stroker they will be going on

are you milling? just regular flat top pistons?


btw if i had it to do over again i would have saved up for some AFR 205's. i kick myself everyday for not doing it. and i reccommend you do this. $2,285.99 from texas speed. it seems like a lot but it's a drop in the bucket compared to the bigger picture.
