EGR valve location may enter into it as well as SouthArk suggested.

Overall, I'm guessing its normal.
But there is sooooo much difference between the two banks. The slight differences in the even-numbered bank looks normal to me (recirc, &c). Even the "dirty" odd-numbered bank don't look all that bad (dirtier than what I'd like to see, but I've seen worse). The fact that the odd- and even-numbered runners are so different worries me.

But I've already proven that I'm no expert.
