Default Max Bore Sizes?

What are the MAX bore sizes for the following engines?

1. LS1 (6.0L iron block)

2. LS2

3. L92

I am deciding on what type of block to invest in. I have at my disposal a 6.0L iron block now, but I think I want a 4.065" bore for my L92 heads. Can a 6.0L block be bored .060? If anyone has ANY info about this subject, please let me know. Thanks in advance, guys.

I would like to know also, i know the 6.0L iron block is being bored out as much as 80 over!!! The min. bore for the L92's are 4.00" so the stock bore in the 6.0L will work

Yes...
I just want to get the most flow from the heads, and i know bigger than a 4" bore would help to unshroud that big-*** 2.16" intake valve....
