Last I heard from the highly secretive world of Formula One, was that they were 
using multiple poppet valves (like 5-per cylinder), opened by a camshaft but 
closed by compressed air pressure instead of valve springs.

They say cooling metalic valve springs at 19,000 RPM is an insurmountable 
problem.

Thats about 158 valve cycles per second! And they race for over an hour!

Eeee-yowwww!
