I've got that same setup and was at 15psi with the stock 6.0L heads. I just put a set of AFR's on, so boost will probably drop a bit, but HP should go up hopefully...

My SCR was 9.45 with stock crank, compstar 6.125 rods, -4cc Mahle pistons, and GM 6.0L heads (these are advertised as 72cc, but they are really like 71.09 from what I have read here). Also using the GM 3-layer 6.0L gaskets.
