StillBlue22, I think I saw that you were talking about timing belt and also resurfacing your heads. It's not all that hard per-say, but it is time consuming. More so on the 3.5l engine. Just be methodical on how you disassemble the parts, organize the corresponding hardware and disassembly order.
Those pictures are rather deceiving. Those heads were pretty filthy. I did wipe them down with a rag just to remove all the surface oil and grime.
