Yea you can go more. You said safely so I suggested .030, anymore than that and I highly highly recommend sonic checking the block to see how far you can go.
As far as the heads, the .030 would help with the valve shrouding for sure, but the bigger the bore the better.

The safe maximum for an LS1/LS6 is 3902 or 383, or at least that's what I have read. Now that's with a 5.7 aluminum block so with a 6.0 iron block like an lq4 or lq9 you have to have more room to play with than that.

Also, take note that gen 4 blocks are a better bet for a large bore. The casting process was better so core shift wasnt as prevalent, but theres plenty of gen 3 running large bores also. But for anyone looking to bore, the gen 4 may be a little more desireable to you.
