I believe the major feature of four valve heads over two valve is they rev higher because each valve is a lot lighter. Flow is not really the problem with a two valve head. Four valve heads work; just take a look at what they have done for Sport Bikes; 600cc's with 100hp.

This is in a holden vehicle. It is front wheel horse power not rear wheel.
This is also on an engine dyno. Not a chassis dyno.
