2010 vs 2011 water pump?

So we have an eagle engine, which i was under the assumption that any 2009 and newer engine had the VVT timing cover, which would make the PS delete idler usable on any 2009 and newer hemi. (apparently incorrect)

So i order my timing cover, it fits up through 2015, so we're good there, bolt on the water pump, and the spacing looks incorrect for the idler, tensioner, and WP pulley....all of which are attached to the WP, not the TC.

so i then look up the PN for the water pump we have, and it has a carryover year into 2010, which explains how it was incorrectly ordered, however it does Not explain why 2 years of the VVT engine got the older water pump. i'm now assuming that changing to the newer 2011 WP will be thicker, and thus fix the belt spacing issue? any other input?

for anyone that was on the other belt routing thread, i know i referenced the non VVT engine there, but we actually changed game plans, and i for sure have the VVT eagle engine. just need to know if the 2011 WP is thicker faced for some reason. maybe thats when they went electric PS? and changed spacing? i notice my damper is 2011 and up only also. I figured that the VVT timing cover was the culprit for the spacing change...but you know what happens when you ASSume :p
