Re: Strange new technologies...

To get 3 hp per cubic inch you would have to be turning in access of 14,000
rpm to pump enough air.  Or you could use forced induction; but, then you
wouldn't need the fancy valves to get there.  Fine for racing a 2.0 liter.
Not what you want to drive to the store and back.

Back in the 60's I was very interested in rotary valves as a concept. Not
so much because they would flow more air; rather the possibilities they
would lend  to "variable valve timing".  Problem I saw was similar to
problems NSU, Wrankle & others had with the rotary motor. Sealing. 
Besides, replacement parts for theses would no doubt make the $44 V8 q
lifters ( X 32) seem cheap.
