My engine is in my sig. I was wondering what everybody thought of the 320cfm patriot heads. I know they are a lot cheaper than everyone else and that is what worries me about buying them. Thanks

the ones that flow 296 by patriot are proven to make 36 flywheel hp on a stock cam ls1 with just headers....i have them and made 402whp with 222 cam and ls6 intake....from what i hear, that would make them pretty good.

mind you also that mine are the 296

I'd have to see flowbench results and track results. But in my experience cheap usually doesn't mean the best product. Research will tell you what you need to know.

patriots are a good option for a person on a budget. check out the dyno section. the last few people who posted using patriot LS6 heads have made some good power.

I've put down some good power with my patriots. They're no AFR or trick flow, but they are good budget heads.

Dumb question, dont kill me, but i dont know anything about heads: would these LS6 heads fit in a stock LS1?

Rddragon

I know they are a cheaper head but with a budget i think they will do. I dont know a whole lot about head flows but 320cfm seemed pretty good. This is a street car so i hope they will work. Trickflow and afr are like twice as expensive or i would do them. What should i look for on the flows? Thanks

I'd like to see patriot LS6 heads go up against the PRC LS6 heads froM TSP...

See sig, older patriot ls6's (300cfm)/torquer II /fast 92

so what should i be looking at since i have a 383, 500HP? With the head swap im also gonna do custom pushrods, custom head gaskets, and a crankshaft scraper if i can find one. I also have a decked block so that will probly heighten compression wont it?

many things affect compression. you wont be needing a crank scraper though. gm gaskets is all you will need for a street car

I used felpro gaskets last time my heads were off, but a high performance instructor at school told me about cometicgaskets, their products look good so i was gonna try them. With how much it takes to do a head gasket i want put some good ones in there.

Yes. LS6 heads on an LS1 are probably the most common head swap.

And, there have been plenty of outstanding dyno and track results with the PP heads. Price to performance, they're tough to beat. But, so are most of the other budget heads. You do get what you paid for, but for a street car, I'd say they're by far "good enough."

Now, I wouldn't put budget heads on a 383, but that's just me. And, no, you'll need a pretty stout setup to make 500rwhp, and that includes premium heads.

Do a search for 383 in the dyno section.

i have gm gaskets in my car and thats all about i run. and for fraction of the cost of the cometics. u will need to know how much your piston protrudes out of the bore to make your decision on gasket selection. .035 -.040 quench is excellent for street n/a

Rddragon

Like go to GM and OEM gaskets? Is there anything that is bad about putting pp heads on a 383? or is it just not the greatest move? i have a terrible budget, so i cant go to big on heads. Thanks for all the advice guys

a 383 warrants hi flow heads. should look into sending your cores to TSP nd let them run there cnc program, for budget purposes. maybe save a few bucks over the patriots. the mls gm head gaskets peform just as well if not better in some occasions over the cometic.

Just an FYI

if it would make over 500 hp i would be hella happy

But last I checked PP doesn't weld up the chambers anymore so being a stage 2 head with bigger valves that cam would prolly not clear on the intake with that cam on their newer heads....

Not a knock on PP just a FYI..

If I were going OEM head I would look elsewhere. I would gladly pull my ported OEM heads this weekend to put towards some AFR's if I had a firm buyer....
