Looking for bore thickness (ls6 / ls1)

I thought I have read somewhere that the LS1 block cannot be bored due to thin CYL walls. If you'd like to bore the block you need a ls6 or C5R block?

Anyone have the specs for the cyl wall thickness on these two engines.
I tried Googling and searching on here, but to no avail.. Looking for a comparison.. I

Thanx in advance!
