They will vary, but even boring it to LS1 5.7 over bore size (3.905) they should be checked to be sure they're still thick enough.

i was under the impression that 5.3 and 6.0 blocks were the same except for the bore?

I wouldnt of thought that to be true because they wouldnt waste time boring the same block to make a 6.0 when they can just cast them for the bigger bore.
