pro design manifolds

what is the diff. between the manifolds for V-force reeds and non-V-force reeds, any help would be appreciated, thanks Brian

One is made to be used with V-Force reeds and one is made to be used with stock reed cages.

i understand that but what is the the design differrence between the two. pro design's site just says there is a "slight difference between the two" sory if i was unclear

on the V-foce model, the reed side of the manifold is machined smooth since the Vforce reed cage has a built in air diverterto direct the air down thought the reeds. the standard version for stock reed cages have an air deflector plate mounted on the reed side to channel the airflow. I learn that the hard way and had to grind off the plate to fit after I realized I ordered the wrong one.
