GM CNC LS6 heads

GM CNC LS6 heads
Was digging around and found that GM high performance offers cnc ported LS6 heads for $1500. I was wondering if any one had these or knows how good they are or about how much hp they will make. Its going on a 2004 GTO and will most likely be paired with a lingenfelter GT2-3 cam.
Thanks,
Mike

I looked at other heads, but 2200+ for AFRS are out of my budget. I want a mild sleeper with stock drivability and reliabliity.

Also available in 60.9 cc combustion chambers # 88958622.
For street applications the GT2-3 camshaft works great in combination with these cylinder heads. Priced each $1,140.80
direct quote from the link you provided
so the afr's would be cheaper .

I am currently running these heads, got them for less then a 1/3 of what they sell for! Only downside is how big they are(245cc intake runner) for a 346. Great heads, makes great power, and thats that. Also, mine are the 60.07cc heads

I just finished building a 408 with these heads they flow excellent.
495rwhp and 470rwtq
I had the smaller cc heads on my ls1 and the hot cam= 402rwhp and 372rwtq
I'm not sure how big that lingenfelter cam is but the hot cam is small @219/228 525 lift
Scoggin dickey has those alot cheaper 995.00

Lingenfelter does nothing but emmision legal cars so I would say it would pass!!
By the way, I am running their LS6 heads and GT1-1 cam, 484 hp/ 440tq via a 383 stroker on an Ed Wright tune, recently installed Kook's 1 7/8 LT'S/ORY and had it retuned by Chad @GreenlightMotorsports...should be over 500 HP and 450 TQ now.

Do they have flow numbers? I remember some of the old LPE portings stalling out at .550 or so. If you are running a .581 cam, I would make sure the heads flow up that point.
