I'm going to hazard a guess that Daytonas originally having sodium-filled valve stems (notorious for bending) may be part of this story.
Many, many Daytonas have been known to have this or something very similar happen to them in past 4+ decades and AFAIK, other than perhaps questionable (relatively new at the time ?) manufacturing technology on the OEM valves, no common cause has been identified. Car/engine could have only few thousand, "softly" driven or tens of thousands "WOT" miles when it "just happens". Probably not very many (Daytona) engines out there still running their OEM valves. I know only couple.
Out of interest is this an issue that is most prevelant in Daytonas or is it common across all Ferraris of the era. I know my mechanic has rebuilt a couple of 246's after valve failure and a 365 Boxer which did huge amounts of damage but it seems to be most talked about when it comes to Daytonas or is it I just read about Daytonas more
While my (limited) experience and researches extend mostly to Daytonas, I've also heard/read of other models of same era having had similar valve failures and if assuming Ferrari used same valve supplier for all their engines during that period, this probably would've been a common issue in all of them.

because of no number plate this car was used for racing, and then it would be normal to lower the car a little
