The end of the Ford flathead V-8 came when Oldmobile introduced the overhead valve "Rocket" V-8 in 1949. You just can't get the performance out of a flathead that you can an overhead valve engine. But the flathead design lived on for many years in low-performance engines, particularly small air-cooled engines and marine engines like the Gray Marine (Chrysler).

I believe the main reason that small engine manufacturers are these days going to overhead valve engines is to comply with emission standards, rather than to improve performance or reliability.
