I'm a little baffled by this. I've been hearing for years that the 2v exhaust port actually flowed better than the 4v exhaust port. The opposite of what you are saying ?

4V heads flow better without a doubt! As Doug pointed out, 2V heads are purported to make more low end torque and offer snappier throttle response and off idle performance in a street driven Cleveland because the smaller intake ports allow for higher air/fuel mixture velocity at lower RPM's. But 2V heads will not outflow 4V heads!
