I saw your other thread as well. Interesting that my 2013 engine is considered 776 AB. I wonder what the change is other than 5w20 oil.

My sense is that the AA, AB, etc notations are simply suffixes to identify minor part revisions and that any part can have them, so you will see varying suffixes all over the vehicle depending on how many times a particular part has been revised. The important one is the part number on the left head.

Where is the Pentastar head's part number located? Is it visible without taking things apart?

The first pic is the head sticker on passenger side, just remove the plastic shroud and it's right there on top. I wasn't able to locate anything on the driverside head that I just had replaced.
