The only thing to solve this is using rotating valves. Once I have seen an engine using 2 rotating tubes above the cylinder, one with an hole to the cylinder to let the fuel through the tube in and one tube with a hole conected to the exhaust.
we've been over this it's pneumatic valves springs for high rpms.
a metal spring horribly slow compared to pneumatics.
drag is usually reduced by rollers on the cam, rocker or, lifters
a big tube with holes lol that sounds so silly but yet probably the easiest to seal the valves
you'd till have the drag of a chain, belt or gear, in that.
just make sure we can use turbo plugs on this compatibility is the key Dp-buggy wants here
