6.4 Hemi Ticking

Hey Guys,
I came across a deal I couldn't pass up for a '13 6.4 out of a charger. I heard the engine run before it was pulled and had a slight constant ticking at what seemed all rpms. Supposedly dealership had determined it to be the wrist pins. All the research I have done, the wrist pin problem was narrowed to the 6.4 trucks and only ones built during a few months timespan. I was wondering the chances of if being the mds lifters? Other things to look at before I pull it apart and check clearances?
