I just got my 2.0 heads back from Len (Hoffmann automotive) and they are beautiful. It'll be weeks before I am ready for them but photos will be forthcoming.

In the meantime, I muse about valves...since fuel injectors can be precisely controlled in timing and range of movement, with stronger electronics of course, could not intake and exhaust valves be moved electrically thereby allowing variable timing and maybe even reach.

Yes modern cars have variable cams but wouldn't electrical valves be infinitely varible?

Surely engineers have considered this. Enlighten me if any of you know. Thanks.

Rotary valves. No valve springs... no valve in the way of the airflow. Just a nice open hole. No chance of the piston hitting the valve in high compression engines. No valve float. Simplified valvetrain, just a shaft with slots cut in it.

First invented in 1886. Never perfected. No one was able to overcome the radial sealing issues with the shaft.
