  1. I take it you mean the ones like Opel used to build. I had a Renault that was OHV but had the cam placed so high in the block the tappets were in the head. Plus it was a hemi.

  2. What is the engine designed to do? What RPM range is it expected to operate in. Lower RPM OHV is perfectly acceptable. High output low displacement. DOHC w/4 valves per cylinder.
