DeTom,
Thats been tried, engineers had a hard time with the exhaust valve, it got too hot & failed. F1 cars are already turning 18,000 rpm or something like that, just copy their system! No need to duplicate effort.
BMW has developed a solenoid operated valve actuator that elimates cams, cam followers, etc; does it all electrically.
Besides I'm retired from working on cars other than my own, and I hardly want to do that! But I'll tell you what I will do! I'll drink buttery nipples until I make the room spin 10,000 rpm!
your dizzy friend on the PIBB, George
