I might be missing something here, but what is the difference between an 8 valve engine if it had large valves, and a 16 valve engine?

Surely the gap the valve makes is more important than the number of valves?
 
Also some 16 valve engines only use 8 valves at low rpm and all 16 at high rpm to give a good balance of power and economy.

Interestingly Audi on their 1.8T head used 2 valves for the exhaust but 3 for the intake making it a 20 valve engine.
