Default GM Accessory Pulley Alignment

I installed a complete 2010 Camaro accessory drive onto an L92 from a 2007 Escalade. I noticed that the crank pulley/dampner is about 1-2mm too far towards the block - about 1/2 a groove. All other pulleys line up to each other.

Since there is nothing to adjust with respect to where the pulley winds up on the crank, it would seem to me that there must be an acceptable production tolerance for alignment rather than a requirement for perfection. Are there any specs on what is a reasonable out-of-alignment and am I ok?

Did you get this figured out? I also have an L92 (from an 07 Escalade) and will be using an LS3 intake and was considering a late model Camaro front drive system. Does the system fit with the VVT or did you disable the VVT and change the front cover?
