patriot heads, are they worth it
patriot heads, are they worth it I was looking to purchase a set of patriot heads for my 408 turbo block but i was warned off about them. i was told they was garbage so im here asking have anyone on here have they used them and how did they work out? thanks for you help
I dont think they are garbage at all, BUT WITH A TURBO 408 YOU SHOULD STRONGLy CONSIDER THE THICKER DECKS OF THE AFR HEADS TO RESIST HEAD LIFTING . Crap, sorry about the caps... Some folks claimed the smaller chamber Patriots (filled via weld) would not be strong enough to deal with the turbo/blown projects (due to potential chamber weld failure). Im not sure this was ever proven and I remember Gunner from Patriot explaining it was hogwash. I have seen good results with patriots when dollar cost averaged.
I'm using some LQ9 stg 3s on my build that should be done in a week--two.
I ordered stg 3's but my flow sheet (provided by patriot) showed slightly lower cfm numbers than advertised....as well as different valve size than advertised.
Weird I know, but the numbers still looked good for a thousand bucks!

I have them on my 422 now untuned
I love them for the little bit of driving on them the work great so far. I had no issues putting them on everything bolted up just fine. I saw no bemlishes or anything. I agree for the thicker deck and what not but there are people pushing 600+ with stock 317 heads now. I have the stg 3 6.0 heads 208 160 And luvem!

As far as flow...advertised:

AFR is the best. seems like u got the money, spend it. we've installed AFR heads on numerous FI cars and they've been golden every time. from what i've gathered, patriots are hit or miss. work for some people, not for others. with AFR, you know you are getting a superior product that WILL perform, every time. they flow great not only at high lift, but all the way through. added benefits are the thicker deck, the optional inconel exhaust valves which you will want, and the good springs.

I bought a set when my project all began..... had to have them gone thru..... valve job was CRAP, new valve seals.. etc.... In the end i spent as much as i would of for a nice set of AFR's. Have a good shop check them out if ya do get them. ya dont want to destroy a $5K short block from $1K heads.....
The Patriot Gold valve springs are awsome though..... they speced out higher side by side then the comp 921's i was going to use.
Thats my .02

The numbers being lower is because the advertised numbers on our website for the stage III were taken using a 4.125" bore. The numbers for your heads were flowed on a 4.030" bore to closer represent how they will perform on your specific application.
As to your flow saying 2.055"/1.57", this operator on this test simply overlooked changing the specs. All of our heads are flowed, vaccum tested, and pressure checked before leaving our shop. Our heads are of high quality and are availabe at a great price. The products we use to build our heads are the best on the market, Ferrea valves, Patriot Gold springs, brown viton seals, machined spring bases, Super 7 machined locks, ti retainers....only the best. The valves are hand lapped and each head is assembled by our shop foreman who has 15+ years of experience.

I take it that wasnt the same almost 2 years ago when Terry was there............
Because we know what we saw.If all above it true now thats fine...... really it doesnt matter who's heads they are always have a once over with them before they go on the car.

I cant personally speak for their pruduct...though i have not seen any complaints, but Patriot's customer service is INCREDIBLE, gunnar spent over a hour on the phone with me helping to figure out a setup, even when i decided to go cam only and not buy the heads
great guy to deal with, thanks gunnar

Thats BS comment!The work at Patriot is performed the way the owner wants it done,not how I wanted it to be done.I wasn't in charge,I just worked there.It wasn't my decision on what brand parts to use.I didn't perform the assembly,I was just the contact on LS1tech.The work that was performed at Patriot when I was there is performed the same way as it is now.The only difference is now they use better quality valves,and I agree the person assembling the heads is better than the workers that used to be there.When you have better people in the shop and use better quality parts you can produce a better product.

I like my patriot heads other then that. i made 421hp at the wheels with my cam, and now i need bigger injectors. plenty more power on tap. damn bastard year '98
well this got me thinking, what should i do. bottom line are these heads good for making the power to run low and i mean low 9's high 8's. Have anybody hit that goal with patriot heads thats the question.
