Outside of flatheads and lawn mower engines most engines of two valve design are hemispherical in nature, ovalspherical, half round, almost-half round, C shape, D Shape etc. The French came up with the Penta or Pent roof design in 1911 for the Indianapolis 500 utilizing the four valve design.
Call it what you will but a dome is still a dome. Domesphere just doesnt roll off the tongue so great. Sometimes the marketing departments were smart.
In an odd move Chrysler replaced the Fratzog with the Pentastar. Maybe one day we will have a Hemistar?
