LQ4 6.0 with 243s will net you a 10:3:1 compression with stock head gaskets. id run 243/799 (exact same flowing head just different cast number. if you get Corvette 24:s you'll have yellow valve springs an sodium filled valves) heads with a NNBS intake an a DBC 90mm TB (the intake is 90mm just like the TBSS intake) id run a 220 or maybe a 224 cam. pacesetter LTs or if the cash is there grab a set of ARH they are 1 7/8" headers vs the 1 3/4" pacesetter LTs. what converter ar you running? 3000/3200 would be awsome!
i wish i woulda went with a 6.0 vs my 5.3
