Default Which ARP Head Bolts do I need?

I have a LQ4 6.0 with LS3 Heads/Intake and don't know which ARP Head Bolts I need to order. The reason its confusing me is because there are 2 different styles offered. Anyone know which set I actually need?

FWIW, the easy way to check is to "plumb" the headbolt holes using a piece of wire or even a pencil. If the outer holes are the same depth as the inner holes, use the 2004+ kit and if they are longer, use the earlier kit.
