Or maybe the springs are more powerful and just plain ol' damage cheaper valve seats...
Tetra-ethyl lead was added as a cheap hack to get around poor fuel quality and part quality in early gasoline. TEL formed deposits on valves and seats that prevented little micro-welds from forming. These little welds ripping apart was the cause of premature valve seat wear... not pressure from slamming shut.
