6.0L equiped trucks/SUVs

Which trucks/SUVs are equiped with the LQ4 and/or LQ9 heads? Anyone know the casting numbers and locations for the LQ4 or LQ9 heads? TIA

I've only seen casting 317 on the 6 liter heads. This head is on both the LQ4 and the LQ9.

What is the difference between 5.3 & 6.0 heads? Chamber size? Valve size?

Thanks
