what other major internal engine change in the past 100 years..
Overhead cams go back before WW1. A 1912 Peugeot race car which won the French Grand Prix was the first DOHC engine. Several WW1 aircraft engines used overhead cams.
There have been lots of refinements and changes in basic layouts. 4 valves per cylinder and variable valve timing to name a couple.
