But look at what pushrod 2 valve V8's can do now days.
In some ways a simple 2V engine can do very well for efficiency due to swirl characteristics that can be designed in. 4V engines generally need to use more tumble, getting ports setup for swirl is hard to package, and doing different variable lift or opening just one to promote swirl ads a lot of cost and complexity.
