Moving to Internal.

 

I would say livernois would be the better heads. They take the 243 heads and port them. I think the cfm maximum are 305.

 

I would go with Livernois. They are 243 casting and flow at 305 cfm.

 

hello, not sure of current pricing but my TSP cost $900 and they claim 307 cfm at 600 flow. guessing 215 exhaust. these have steel valves, not the vette hollow sodium filled stock ones. but mine are cast 243's , thats what i wanted. i probably should have upgraded springs. comes with ls6.

 

Patriot Stage III LS6/LS2/LQ9 Heads flow 320/235. Need a 4" bore for these to fit, because of the 2.08 intake valve.

Pretty good numbers for $1200.

 

Livernois here. They are a great bunch of great guys w/ top notch service. I haven't seen anyone that was anything but happy with their purchase.

 

i like the fact that you can get a real good head/cam package with the heads your getting and pick from a selection of cams for $1700 or so.

 

I would suggest out AS Cast LS1 head. The head flows almost as much as the CNC'd heads and they are priced very well. Here is a link for the heads and the flow numbers.

How much do these cost and do you have to use different rockers?

 

I vote Patriot and you get their great customer service to boot.

West Coast Cylinder Heads. They do a lot of nice work with all sorts of different castings. They put out some of the baddest *** All Pro LSW heads I've seen.

 

Thats a good idea! Port the heads that already come cnc ported!?!?

 

i run the 66cc lq9's with stage 3 2.08/1.6 valve heads.

 

Ok, flame me all you want for what I am about to type, but did you seriously just suggest a 2k set of heads that requires special rockers, flows less then a ported stock head, and is on backorder for almost 2 months??? You guys make nice stuff, but I don't see how you fit in this game.

 

I am not here to flame anyone.

I see your concern in what I am suggesting. Granted out of the heads listed our heads cost more. Basically I am just throwing out there another choice.

 

i was actually about to start this same thread... i have a 224 already in my car so the next thing is a set of heads. or should it be a rear end first? either way im definatly looking into the livernoise and the patriots. its my daily driver so im not too sure if i want compression to be raised... not positive on what it will affect though.

 

I bought my Patriot LS6 Stage II 59cc heads used for 900. I am putting down 480rwhp and 460tq with mods in my signature.

 

I have a set of Dart Heads that were ported by Bo White waiting to be installed? Total cost for heads is $1350.
Another option.

I think these are a great budget head https://ls1tech.com/forums/lsx-parts-sale/869217-brand-new-prc-ls6-stage-1-heads-used-catback.html

 

We would like to thank everyone for their good words in this thread. All of us here at Patriot have worked hard to bring great performance, quality, and service to everyone...just not people with deep pockets.

For a budget set up, we offer our CNC ported 243 castings, assembled with new oem (non-soduim valves), and our Patriot Gold dual springs for $1095.00 per pair. This is a great deal that is hard to beat. Don't forget that we can offer complete head and cam packages at great pricing. Give us a call and we will be glad to over some options with you.

 

What is the market for these "AS CAST" Heads? I would think that anyone who was willing to pay $2K, would shell out the extra $500-$600 to get a set of CNCd heads. I am not aware of how much yours cost, but i would assume they are competitley priced with my AFRs. BTW, welcome to the site. Have heard great things about your products.
