yeup, i believe you can get all of this for the same price of a ported stage 3 ls6 head package. Kinda crazy!!!

Personally, i believe those heads are gonna revolutionize the heads wars. GM really steped up with putting these on the market and at the price they are selling them, well, i dont see why not.

great thing is that we have the manditory 4.00" bore that these heads require, since we are a lq9 6.0L motor. These things flow like C5R heads bcause they were designed after the C5R head program for the ls7.

So, would i, hell yeah!!

TAZ, i would probably want to be under the 10.1:1 CR range. My current car is at 8.7:1 and im shooting for 15-23psi. So a 9.1 cr is a good place to be to maintain a strong dcr under everyday lower boost levels... think about, running 20psi everyday is alot of strain and we need to dvelop a way to acheive peak power without increasing the psi levels if we want the motor to last. Not that it isn't but the more you are throwing at it, the higher teh frictional coifficient... more wear.

So, me.... well, i would start with a larger CI motor, than add a 122 eaton, f that is what you like... and see where that takes you... OR, a kenne bell. With our blocks, all we need is a larger piston, port work... to about 4.030" bore for a 408ci with a stroker crank of 4.00". (i believe or stock strock is 3.62ish) You can go bigger, and increase the bore, and get a 422ci... but a 408ci is fine. NOW, you will have the torque down low and stay flat acoss the powerband.

NOW, you add the boost. 9.1:1 is fine, and with a proper tune, i dont see why you shouldn't net 800hp with a combo like that. That is at the crank.

good luck!!
