With this set up...which heads would you get? I know this has been asked to death, but I want a set of budget heads. I have narrowed it down to Patriots or PRC's.
Patriots are 243's, come with Xtreme springs good for .660 lift, titanium retainers, locks, seals...etc. runner size is 227cc, 64cc chamber, flow 300 cfm at 600, stock size valves $1115 +S&H
PRC's LS6 stage 1's with racing finish, prc dual spring kit ($250 included in the cost below) and I am assuming but not sure if they come with titanium retainers, locks, seals...etc. runner size is over 230 but not sure exactly what size, 64cc, flows 310 at 625. $1300+S&H
PRC LS6 Stage 2.5 All of the above plus 2.04"/1.575" or 2.02"/1.575" stainless valves, and????? have no idea what else but I am sure it means more performance....$1450 +S&H
Here on the mods that are there or will be installed at the same time as heads, car is an 02Z:
MS4 cam
fast 90/90
double roller timing chain
asp pulley
85mm maf
volant cai
Pacesetter LT's with Xpipe dumped
4.10 gears
(thinking about but not sure of adding Rockers with chromoly pushrods)
I was convinced about the patriots but then kept looking at the prc's, I think if I can get gunnar to get me some more aggresive heads I will stick with the pats. So what do you guys think? Which will be more beneficial to my set up? Oh and $1500 is my absolute limit on the heads.

I am going with the stage 2.5 5.3's with the 2.02/1.57 valves myself. I was torn between the PRC stage 1 243's and the stage 2.5 5.3's myself, but after talking with Jason at TSP decided on the 5.3's. He seems firmly convinced they are the best head for the money. I also asked about getting them race finished and he said he would not even do that anymore because the current CNC and program does such a good job on the port that hand finishing them usually only nets a few cfm more and is no longer worth the time. I just hope his opinion is correct.

The cars running fine, for now. We went out to the track yesterday. I was in support mode for Steve. He had three big races, so I was there for tuning and pit crew for him. He put a whoop *** on an Evo that was talking ****, also a S-10 pickup. He ran a 12.4, his 60ft needs work. If he had a better launch and 60ft he would have hit a low 12.
