Headbolt question

I’m sure this has been answered before and if so just point to where the thread is located because I’m not finding it in search but how would I go about finding out if a certain car has had its headbolts changed already?

Headbolts

Don’t see that this was answered. If you pull a valve cover you can see them. Otherwise you’re with service records and checking the engine serial number as far as I know.
