WHY IS SPARK PLUG IN CENTER OF CYLINDER HEAD

1964 Dodge Other • 100,000 miles

The hemi engine has spark plugs that go through the valve cover. Why is it that I see GM and Ford engines doing the same thing now on almost all engines? If putting the spark plug in the center or the head is better why did GM and Ford wait so long?

Better combustion, more complete.
