Ferrea, Manley, or neither?

Topic says it all. I am going to start assembling my heads, and I was just curious about valve opinions. I was thinking either necked-down Manleys or Ferreas, but Ive heard that the Ferreas are lighter and flow better. Is there any truth to this? If it matters, these will be 2.02/1.6s going into a set of 200cc aluminum ProToplines.

I kinda doubted two brands of valves, givin the same size, backcut, etc, would flow much differently, thanks for the response.
