When was the last time you saw one of these (mystery race engine purchase)

The ATI’s come with instructions telling you that it’s pretty much mandatory to fit the damper to the crank.

I think it should be “SOP”.

I'd say 50% of the ATI dampers I check have a loose crank bolt. Strange things happen when the correct press fit is not achieved.

As stated SOP to check them. A lot of people start them with a mallet and run them down with three quarter inch damper. I have also seen my fair share of ugly crank snouts from a tight damper.
