One thing would be the valley pan. If it's smooth on top then DoD is removed. The DoD valley cover has visible pathways for oil on top.

That is what I was thinking. The valley cover would be the clue.

IIRC, the cover can still be a DOD version. The "tell" would be if the DOD lifters had been replaced with standard ones...

While I would assume that if someone when through the effort to install a new cam then they would have also mechanically eliminated AFM, I suppose it's possible that they wouldn't have.
