If it's an Iron block and has 6.0l on front of block:
LQ4/LQ9 - Gen III, cam sensor in the top rear of block
LY6 - Gen IV, cam sensor on the front timing chain cover
Aluminum Block and 6.0l on the front:
LS2 - Gen III, cam sensor in the top rear of block
L76/L98 - Gen IV, cam sensor on the front timing chain cover
On the LQ4/LQ9 the only difference is the pistons, so no visual external differences as far as I know.
