Default max bore on a 6.2L Aluminum Block (LS3/L92)

How much can a 6.2L block be safely bored. I am looking at a L92 Motor that I have that dropped a valve and It needs to get cleaned up in #1 from a inch long vertical scratch. Just want to be sure the motor is worth it before I dig into it.

And since they start at 4.065 (or is it .062???) .015 is not much.
