LS2 bore?

Is the LS2 the same bore as the LS1/6?

The LS2 cylinder heads (243) are the same part number as the LS6 (243)

If they arent the same bore, is the chamber opened up at all on the LS2 head?

and is the C/R the same in both?

Thanks

LS2 is a 4" bore (LS1/6 is smaller..3.9xx or something). LS2 heads are identical to LS6 heads without the hollow stem valves.

Thanks,
I thought the LS2 had a 4" bore, but when I saw the 243 heads were basically the same, it had me wondering.
