    They look exactly like the stock heads i have on my car... $1400 WOW little pricey huh!!!

    All i know is that i'm going with the Patriots because with the extra 10 that i "MIGHT" from the AFRs for the extra $1100 aint frigen worth it!!!

    Now for the FINAL verdict!!!! Which LS6 Patriot heads would be best???

    1) Patriot LS6 5.7 - STAGE 2 (2.02/1.57/64cc) or the 59cc version?

    2) Patriot LS6 5.7 - STAGE 2 (2.055/1.57/64cc) or the 59cc version?

    3) Patriot LS6 5.7 - STAGE 3 (2.08/1.60/68cc) <--- This would be my choice!

    I picked the last one because it appears to have the best flow and isn't crazy big like the LQ9's and in seeing that i will be N/A for awhile i think i could be able to squeeze the most HP with the Patriot LS6 5.7 - STAGE 3 (2.08/1.60/68cc) or 64cc..

    This will be my final decision so i would appriciate all input, tech information, dyno numbers, possible HP and TQ i'll gain and anything else you might think of!!

    I was ripping SLP. I don't know they are stock, I would hope they aren't.
    And man....you should be faster with heads and a cam. 12.59 is bolt-on times. SLP just is simply overpriced and the product could be better. Customer service is SERIOUSLY lacking as well.


    I went with option #3 myself. Except mine are 62cc.
    The intake valve is a little big for stock cubes on the Stage III. I would have probably have gone with the 2.055/1.57 heads for stock cubes.
    Either way....good choice. Let us know the results!!

    Are you stock cubes?? What would happen if i did the 68cc intake on stock cubes would i actually loose HP??

    And would the option 3 with the 62cc like your be good and how much gain can be expected?

    My car gained 69HP from selection #1 with 59cc along with headers and a tune, granted i had a cam that was being choked at the time also

    I am not stock cubes man. I am working on getting my 402ci back into my car.
    I went 62cc to bump up my compression to 11:1. I also have dished pistons giving me much more room to run a larger cam (248/254 629/622 113). My heads were the Stage III 64cc but I had Patriot mill mine .020" making them 62cc. I am also running Cometic .045" head gaskets.

    With 68cc heads, stock pistons, and stock head gaskets you are looking at 9.8:1 compression. I think the little compression you lost would be more than made up by adding the heads.

    The problems they had were fixed over 2 years ago. PP hold their own with AFR, depening on Application one beats the other by a tie going to PP for cost, or AFR by 10-20HP and TQ. if you have a huge cam or bigger cubes. I would stand behind AFR 100% unless you want to spend the extra 1k elsewhere. if I was going all out on a motor AFR, but in my application PP actually outperformed one of AFRs head models. http://edigras.iweb.bsu.edu/headscam.htm

    If I get what I pay for, then I should go out and get a new 20k civic with all the options, because it costs more than an ls1 camaro so that makes it better. So now I should be able to blow it away then...

    Quality isn't the highest price on the market. You're just bashin Pats, tell us of this company and give whatever reason

    That is a terrible comparison. Brand new car priced against a used car.

    I am NOT bashing Patriots.
    But AFR > Patriot.
    At least in the heads, not sure about other things like customer service. I do know that Patriot has some KICKASS customer service. Gunnar helped me a TON with my set.

    this is like a year old thread..so what did you do NeeD4SpeeD?
    I'm planning to get 205cc AFR and Cam kit within the next 6 months. right now doing the LT H & Y at LG Motorsports in Wiley TX. the AFR head and cam kit would net 110+ rwhp and then some +20 after a pro tune... it would put me into 470rwhp range after that.
    can't wait

    Texas Speed has had issue with Patriot heads and Dart heads, me thinks there is something fishy here. The only heads they haven't had issues with are their own and AFR's. Look closer and you will see a pattern here.

    With an aggressive cam, it is possible to see 470 RWHP with AFR 205cc heads. It's not likely but is possible.
