Correct. I am running a set of four bolt ET Performance LS7 heads on a resleeved LS2 block. Most LS7 heads require a minimum bore of 4.100. ET Performance make two LS7 heads. One will work on a 4.000 bore or larger.

1) No, the intake valves are too large for a 4.00" bore. Yes, if you replace the seats and valves with 2.15" or smaller intake valves. Quite costly though.
2) Yes, if you shim them to the proper installed height.
3) No, and there's no need since the LS2 port is narrower.
4) Yes.
5) No, they are the wrong length for a stock LS2.
