Opinions on PRC 5.3 stage 2.5 heads for my set up. Hey guys,
I have done a lot of research on heads but I also value your guys opinions seeing I'm not the most car savvy dude. Looking to upgrade heads on my 2002 trans am. I will list mods and #'s at the end of the post. Car is mostly a weekend street machine. Driven on nice days to cause a little trouble haha. My goals aren't super high and even in the future do not see going over 440hp. Prob be happy with around 425. Car has a smaller can that I plan to keep seeing that I purchased the car because it already had a lot of stuff done to it and was a great price. I might possibly go with a little bigger cam in the future but that's wayyy down the road. I just don't want to hamstring myself by my choice of heads. Thanks and I appreciate all and any input.
Car was built up by vengeance racing but purchased from the owner in the Chicago area.

Can't go wrong with them. I've had them for over 7 years now and still putting down good power. Even going with a bigger cam down the road you'll be fine. I'm running a Torquer V3 (231/234 .643/598) in my set up. After seeing more and more head choices come out over the past few years and making roughly the same amount of power, I'm sold on them.

Thanks for the the help so far. I'm going to have a shop in the Chicago area do the eventual install but I would like to purchase the parts myself. I know the basics that are needed for the swap (gaskets, ARP bolts etc.) just trying to get a parts list together and learn which parts are a must for the swap and which ones are not but still good to do while in there. thanks for helping out.
