What's 'wrong' with patriot heads?
What's 'wrong' with patriot heads? I'm looking for heads for my car, and I keep hearing bad things about the patriots. Can anyone help? I've done searches and haven't goten anything concrete to tell me why they are bad...
Keep looking.....really all I have seen here is a few valve drops and old style seals leaking but the new heads are supposed to have the better seals and buy the heads with the upgraded valves and shouldnt have a problem. Another thing is pay the extra money for them or FFHP to hand finish 'em for ya.
i think that was with the old heads, as in they changed the way they made or the products in them. as of now i think that everything is straight, but i am not 100% on that
There's also the variable of installation workmanship, which Patriot has no control over.
The risk of selling to an audience like us is that you have a few people with no clue how to use a torque wrench or angle-torque meter, don't understand the need for sealing surfaces to be spotless, etc.
But they'll post to the world that your product sucks when things don't go right...
I'm not affiliated w/ any of the vendors here, just my perspective as an observer.

i have set of their 5.7stg.2s on my car.(i put them on last jan.)before i installed them i checked out the valve seals and found a couple that were torn.THIS WAS THE TEFLON SEALS.now they use the vitons,which is what GM uses.i called patriot and they sent me new vitons free of charge.yes,they had some QC issues then but i think those have been worked out. i would get the Manley or Ferrea valves(both are high quality) if you decide to buy a set.i didn't quite get the power i was hoping for but,IMO,my cam is too small for the heads.the intake ports are pretty big,if i would have gone with a cam in the 230 deg. duration range i think it would have worked out a lot better.and to my knowledge,nobody has broken one of their dual springs yet.

I talked to Gunnar@Patriot through PM's and he told me there is a 100% money back gurantee on them pre-installation. This means the buyer can have ANYONE oduble check the heads. Flow them, inspect them, you name it. They will cover them 100%. After install if there is a problem, they will inspect and repair or replace the heads, as well as provide new head bolts and gaskets for the reinstallation.
IMO this alone shows the company is serious about quality. Assuming they stand behind their word on the warranty it goes a long way toward helping me make an informed and secure decision.

PP heads are like a crap shoot, some are good and some are not.
What is the point in buying cheap heads, have them upgraded, checked by other vendors or mechs, you'll end up paying close to what a good set would cost.
Honestly, would you rely on a $2 valve to hold its own with a $4000 block? I know I wouldn't.
You get what you pay for period.
i will be posting independent flow numbers with an ls6 intake in a few weeks. Gunnar sent me a set to test out impartially. here are some pics (no 56k). from a visual standpoint they look great, better then my stg1 FFHP's. for 100 bucks you can upgrade to Ferrea valves.

I believe they get done so cheap because they have paid off alot of their equipment resulting in relatively low overhead.Not all things that cost less are cheap and not all things that are expensive are better.
How can you fault a company for having been financially responsible?
Patriot heads flat work. I have used them and had 0 problems with them.
The old springs sucked ***, broke one spring got them replaced with what looked like the same old ones.
This time the springs didn't break, but I have 8 bent valves, two valves left nice marks on the #5 & 6 piston.
The heads do work, with the new gold springs you should be fine
