looks like i'm in the market for new heads. i have the g5x2 cam,kooks w/offroads all boltons,12bolt w/4.11's with a m6. i was looking at the ls6 heads they seem to have good flow # but i have a few questions.#1 why no core charge on any heads??why a low price$ this seems strange for a ls6 head. #2.how is the quality? #3what are some dyno#'s? #4 what are 1/4th mi times?#5 would they work well with the x2 cam 600+ lift? #6 how long has patriot been doing ls1 heads? #7 should i go with 5.7 or 5.3 heads and why? i see it said the ls6 head will lower compression i want the most power so this is not good ,right?. if their is anything else you can tell me that would be cool. THANKS, mike c.

its an ls6 style head...actually a 6.0 head with the chamber welded to produce a higher compression ratio & then ported extensivly, I personally think their quality is very good their springs are considered amongst some to be the best dual springs out right now, and the heads look good(ive got pics of some on my site including mine), check the dyno section for #'s just search patriot, check out the drag racing section for times, i would think they'd work well with that cam, theyve been doing heads since ive been on this board...i think they started early to mid last year though, now if your talking 5.3 vs 5.7 the main difference is higher compression without loss of room for a larger cam...the 5.3's have a smaller combustino chamber but dont sacrifice room...whereas to get the 5.7's to the same compression ratio youd have to mill them and possibly loose area for a larger cam...other then that once put through a cnc program they are basically identical.

We've got a guy that in his spare time aside being a chiropractor that has gotten very good at openning up some LT1, LS1 and LS6 heads. He did a set of LS6 heads for a guy we built a motor for, which ended up being only slightly bored with a fairly aggressive cam and good tune and he put down 425 to the wheels through a 12bolt in 105 degree weather. We are in the process of putting together a good h/c combo including heads ported by "Cliff" with a spec'd out cam to match. If you are interested in a set, you pick your springs and valves call 405-721-2430 and talk to Robert about them, he can give you all the flow numbers and everything. Our site and merchandise is not dialed in just yet so we are not a sponser yet, but hopefully this response will be OK with the moderators.

Otherwise, Patriots are pretty good heads. We've done a few on customers' cars but when I do heads this winter I will have Cliff do them.

from what i've seen the PP "ls6" heads dont put out numbers any better then a stg2 5.3/5.7 head from any other vendors.

If I was spending 1800 on heads I would just spend another 300-400 hundred and buy afr`s .

To each his own but I would rather spend another couple hundred dollars to get a set of real 243 casting heads.

I just bought a set of patriot stage 2 ls6 style 6.0 heads for $1665 new

I too have a g5x2 cam

MY reasons for buying them are:

59CC chamber, since it's welded up there is no worries about piston to valve clearance being the heads are in STOCK form, not milled! thus awesome compression and a huge cam!

after searching I see that these heads with all bolt ons will do around 415-as high as gomer with like 470+

If you can get even the lowest 415 rwhp it's easily worth it!

figure $300-400 for new 6.0 heads online
their spring kit which is GREAT $300, so that makes around $1000 for porting. not bad at all!

CAN you get better HP from other heads, maybe so, BUT look at their prices, are ported ls6 heads worth the $2000 plus core charges of $800-1200? not hardly worth an additional 10-20 RWHP!
we all know the 6.0 truck has has a SIMILAR port design to the ls6's and while NOT getting as great a flow as a TRUE ls6 head, it's damn close.


when you search you will see some patriot problems, but that was just when the company 1st started out. Terry at patriot is a very nice guy, EVEN when you're just shooting the crap with him and he knows you're not even buying them. Hell, I must have called and talked to him 3-4 times and never even bought them being up and down on my decisions of which heads.


then you have the afr's, I was set on them. BUT, look around there are a few great dyno #'s put down by the 205's, BUT they are milled to around 11:1 compression ratio to get that power, they are running that 224 SMALL cam for a reason! PISTON to valve clearance! with the patriots you don't have to worry about that and can run a huge cam like your g5x2 with 11:1+ compression!

I am bolting my heads to the motor today and will have #'s within the next few weeks.

PREDATOR-Z

Yep, But If you already have a "big cam" you could use them at 66cc 10.25:1 CR and get even more power than another head with a higher CR. For you guys in US and the awsome gas quality you have this is something to think about.

On the other hand a 224 with 11:1 that puts out 480rwhp is difficult to match even by the biggest cams, which as we all know run into low trq output down low, iddle and surge issues, in brief not what one would call "street friendly"

Once I dyno with my "Stealth II+ AFR 62cc" I'll post my numbers for all to see

remember most people dont have actual ls6 heads on their car to start with so your talking a $1200 core charge in alot of cases in addition to $2000 dollar heads...thats a far cry from the $1800ish patriot asks for their ls6 style heads.

TVWilkes

The new lower LS6 style stage 2 heads cost $1665 a pair. This is also with ( NO CORE ).

WS-Sick

I think I'll wait a while on heads because I have a feeling Terry has something really good on the way....

Definitely wait for a little while

i was told not to get patriot heads by someone we ALL know(i told him i would not give his name). it all seems funny they want no core,this makes me think the heads can't be all that great(i could be wrong,but it's odd) i'm looking hard at GTP heads,and will give AFR a good look too. i guess it's between GTP and AFR heads.

CHRISPY

They dont charge a core as they pick up a TON of heads direct (Low cost per set) AFAIK none of the other guys have core volumes like PP

They are definitely a great value based head.

Also is GTP still in business?

I personally do not run PP heads (I have ARE's S3 CNC head which are awesome)

For the price PP heads seem to be doing very well

this was posted by MRB00formula in the eastern sect.
My shortblock has forged Lunati rods (good) with forged Diamond Pistons that were Swaintech Coated (good) and a proven G5X3 cam, SLP oil pump, SLP double roller, (both good) ARP head and main studs (good) and ARP rod bolts. All machine shop work was done at the same place your was, and you even called me about the x-pipe setup. The TH400 is from Hughes, as is the converter, with the shifter being the same that was used in the ESP "Silver Bullet"- along with the same NOSzle set-up and EWP. (good, good, good).

The only problem was a toss-up: Incorrectly Set-up Valvetrain (Comp-R's, pushrod length) -and/or- Patriot Performance LS6 heads w/bad seats.

The heads were replaced (along with the lifters) and the sudden hp/tq drop-off disappeared- I suspect due to better valvetrain geometry.

ALL of the parts I used were "the right parts" and if they were questionable- they were replaced. I'm sick of that "parts" alibi being thrown about, because it is baseless.

I know he bought those Patriot heads around 3-4 months ago.

I have the Patriot 5.3's and they perform great. Very good for the price also.
