Default the ls2 and the ls6

is the ls2 a better block vs. te ls6? i know its 364 vs. 346, and obviously my next question is Ls6 heads MAXED or a set of Ls2 styles...etp/afr. since im boosting, im guessing the 6.0 head would be ideal. Thanks...
(what i mean is are etp and afr heads, based off the Ls6?)

if boosting i would try to use a 317 casting head. since its 72cc i do believe it will help with the CR your looking to acheive. as for the question of which block. personally larger cubes help with a turbo. more cubes less amount of boosted needed and easier on te setup or get greedy and go for broke or break or bust, chose one

The LS2 and the LS6 both use the same head (the LS6 head).. seems from your post that you may think that the 6.0L LS2 head is different..

but still, is there a factor between ls2 and ls6 block? as far as which one excels in durability, and boost handling : after seasoned sleeve and forged internals...

I believe ETP and AFR use their own castings...As a rule of thumb you dont get as much return on investment for a good set of heads in a boosted application....Not to say that the ETP or AFR will not make more power, it is just not as critical in a boosted applicaiton as it would be N/A.
