im gonna buy both and lie to get a set of heads lol

 

honestly get what you can afford, and drive it like you stole it. Im sure we have all sceen a car with less dyno horsepower outrun a higher horse car. But for the sake of ***** and grins i would go with prc ls6 stage 2.5s.

 

i hit 402whp with a 222/563 cam through a stalled 4l60e with patriot heads, and bolt ons with a stock ls6 intake, stock MAF, stock TB, not bad IMO...but unlike most people i will not bag on heads i have never run, so i will not claim they are better than prc, maybe they are, maybe they are not....if you havent personally run both sets and dynoed back to back, then shut up....and even if you have...if you are competent you should know this....one head may make more power with one type of cam, while the other head may make more power with a different cam, for instance, the patriots flow high on the intake, so a cam with a longer duration will shine with those heads, (i am not familiar with prc) but pretend for a second they have a pretty standard intake to exhaust flow, a reverse split may make more power with a prc head.....everyone just goes off what they hear, and their opinion is completely worthless if they have no hard evidence i.e. back to back dyno pulls with mulitple cams. thank you, enjoy the rest of your day fellas

 

if you outran patriot cars which made more power than you did, they didnt lose because of the heads....THEY MADE MORE POWER THAN YOU!

 

Peak power isn't everything newb.

 

I've ran the patriot ls6 heads NA and with nitrous and it made excellent power. Liked them so much my boosted set-up will use their 317 heads.

 

I just picked up a set of Patriot CNCd 243s and couldn't be more happy. It put up strong numbers, right where I wanted to be. That being said, I cant speak for TSP PRC because I have not run them.

 

I'm using the TSP 5.3 heads with a baby 222-222 cam & with my circuit racing always out perform later model LS engined cars with bigger cams & all sorts of aftermarket heads.

 

thanks old school, 400 posts on here and i learn something new everyday....

 

Let me get this straight. You've got over 400rwhp, a stalled automatic car, and you're still running 12s, with trap speeds in the mid teens? Right?

 

i will break this down again patriot stage 2 ls6 heads, comp 222/222 563 563 114 ls6 intake, full exhaust, udp, slp flowpac and a 2800 stall......so ill explain to you that the cam listed above isnt much bigger than the ls6 cam, and the stall is only 1000 than stock, also running a 323 gear,....402/381 12.06 114....road race tire....how much faster do you expect it to go...it is less than a tenth from 11's without a DR....also ran this with 02 codes ....not that that should matter anyway bc i think i ran a decent time even if the light was off for havin a 323 small stall and small cam......not to mention 402 is hardly over 400hp and torque is a decent amount below.....now that i have retyped this hopefully that will clear up any misunderstanding you may have had....would you like this in large crayon?

 

ohhhh i got it...it must be my "junk heads"....that would explain EVERYTHING....p.s. torque is over 325 from the start of my pull at 3500 all the way to the end of my pull at 6500....if they dynosheet is not indicating that my heads are failing me can you please explain to me basically how the numbers are there across the pull from start to finish, but somehow the heads are still making me slow? i think im missing something here, please explain,...actually i take that back, please dont, i will probably get dumber from anything i read from you, just like everyone else on this forum.

 

I've ran some patriots on my camera. And have had great success with them. I was going to go with afr. but patriots cost is what made me lean towards them.

 

On your camera? What kind of camera accepts patriot heads?

 

I love my Patriot 2015s. For the money I made excellent power and have ran excellent times for what little setup I have.

 

If you think peak power always wins you obviously havn't learned enough here.

 

I run Patriots on my 403 in my Z06. They are a good head for the money. Their is a lot of hype with cylinder heads on the internet. A lot of guys pimpen for their brand or there shops brand.

 

bro...im not tryin to belittle you but ....jeeze man...2 posts up from yours i posted sayin how my car makes a minimum of 325 ft pounds from the start of my pull at 3500 all the way to the end of my pull at 6500....kind of contradics your claim that i think peak power is everything.......i love how if anyone even mentions peak numbers everyone always jumps their s**t trying to claim "eh eh duh eh...peak power isnt everything eh uh uh"...never said anything about it bro

 

are the patriot gold springs that come on them pretty good springs???
