F1 engines don't use air pressure to actuate the valves - they have conventional camshafts. What they do have is air cylinders that effectively act as the valve springs. I don't think current metallurgy can come up with a spring to withstand those rpms without float, etc.
Someone years ago tried using electric solenoids to operate the valves, but their response time sucked. You only have to envision the speed and rate at which valves are opening and closing in our engines to see that this would take one heck of a solenoid valve to do it electrically.
The fact remains that the conventional way of operating valves seems to work just fine.
