4.8 or 5.3 for boost?

everyone in this thread is referring to old 4.8 vs 5.3 most of which is invalid for the Gen IV engines.
The 08 4.8 is roughly 9.2:1 compression, probably flat top pistons, 243 heads.
The 08 5.3 is roughly 9.9:1 compression, probably flat top pistons, 243 heads.
if he strickly wants to run boost and can't located a 5.3 RCSB the 4.8 would be a fine choice.
