Generation IV Internal Engine - l92's good for boost?

what is the best GM casting head for boost? looking to start a new build, lq9/ls2 about 9:1 compression and stock cubic inches and a forged bottom end, Blowthrough, my SBC has some miles on it now and i always wanted to go back to an LS

Ls9/LsA

Ls9/LsA

duh completely forgot about that one :bang: :bang:

and any GM lsx as well, with 6 bolts per cylinder will be my choice "from Gm" .
