One of the biggest improvements gained in recent years was the advent of the shaft rockers. It stabilized the valve train signifigantly. Prior to that you were on borrowed time over 8000 RPM in an endurance application with stud mounted rockers. Just too much wasted motion. The valve train is the key.
