I thought you had the casting number 12561168 ? Which would make it a Ls6 block. Also with all the head bolts being the 4" that makes it 04 or newer Ls6.
It also does not have the indents I pointed out in my picture that ls1 blocks have but Ls6 blocks do not, like yours.
If I had to guess I would say it absolutely is a Ls6 block from 2004 or newer.
