Manufacturing oval valves/pistons would be a lot harder than round ones, but would be able to be done.

I was at a job interview this morning, and one thing the place was doing was looking at lathing oval pistons. The cutting head just moves back and forth bloody fast and in time with the rotation of the piston. Apparently few places are doing it, but I don't think they can get the spindle speeds high enough to make it viable for mass production yet.

Ford E-Max engines have oval pistons. Though it's oval by only 1mm or so.
