Jon@texas speed, i emailed ya.
"Hey I have a few questions for ya. I’m looking to get heads this spring, but I can’t decide whether or not to go with the PRC 5.3L 2.5 heads for $1134 (with double springs), or to go with the AFR 205s for $2300.. I know a lot of people make 440whp on the PRC stage 1 heads with a decent cam…but my goal is to make upwards of 460-470whp through my 10 bolt. My car is a 6 spd manual, and I’m running a FAST 92/92 with g5x3 cam combo on stock LS1 heads that currently makes 420rwhp. My main thing is this… Is it worth it to spend the extra 1200 on the AFR’s? I know you’re probably paid to say no it’s not, but I just want pro’s and con’s. I’m wanting a great n/a street sleeper, and my tuner is pushing me towards the AFR’s saying you’ll make more power throughout the rpm range under the curve, not to mention probably making 10-15whp more at peak power. What are your thoughts, as I am very interested in learning more about your PRC 5.3L stage 2.5 heads. edit: Since doing more reading, I'm also interested in the v2.5 LS6 heads and the PRC 215s too. Whichever you think will net me 460+rwhp n/a and still able to run pump 93. Thanks for a prompt response!
-Tony
Also, if you have some customer or shop cars that run these heads I’d like to see what kind of power they make with mods similar to mine. Thanks again!"

should be Experts @ da intreweb, help me!seeing how everyone on the internet is a professional!
personally i would go with the 1200$ heads but im cheap

texas speed told me that the ls6 heads out perform the 5.3 in every aspect, and they arent really that much more. but u didnt ask about other heads all u said was 5.3 or afr

maybe start a new thread as an idea the title should read "emailing john force"
then say " hey john i emailed you here on tech to see if you would part with a pair of youre 300mph heads. oh and tell ashley i think she is hot as hell"
just an idea but hell might work .just imagine THREE HUNDRED MPH HEADS with a super secret g9x15 cam
let us know how it works
best of luck

-It's in the wrong section
-Has rendered itself pretty much pointless
-The OP needs to do some more research and realize that A: It's not the heads making the car go 134mph, it's the package and B: Just because a 1-off car on the internet does it, doesn't mean you're going to do it.
Email Texas speed, and await their response. This is the internal engine section. Not the "hey I emailed ya" section.
