While I agree with most of this, I've read that later LS1 blocks are more desireable on the whole because the larger windows cast into the bulkheads were considered by engine builders to be a little weaker. They aided in high RPM breathing and lowered pumping losses, however the block is produced differently than the LS1 block and I believe the aluminum is a little different too.
