4v > 3v > 2v

as a rule of thumb, the more valves the better because it allows more air flow, which could lead to more power because the more air there is the more fuel you can add. But you could also look at it in the way that a 2v engine with two large valves is equal to a 3v or 4v with smaller valves and so on.

2v and 4v also sound so much better than 3v.....it's almost sad.[&o]

Sorry but you can't just put bigger valves in a 2V to equal a 3V or 4V.
Ok draw a circle, now in that circle draw 2 circles that go edge to edge, now repeat with 3 then 4 circles.
You can clearly see 3 or 4 smaller valves will flow more than 2 slightly larger valves.
