Some points to consider:
• The port divider costs money to buy and install
• Many come loose in short order, creating an annoying rattle
• Exhaust pulses for 3&4 are 360 crank degrees apart
• Effects as they are considered possibly only occur when exhaust gas flow is approaching peak amounts (ie, approaching steady-state WOT)
• Throttle plate opening and closing possibly affects gas flow more in real terms
• The original 2V head could have easily incorporated a split centre port - yet Ford designers saw no need for this feature
• You will have a hard time finding people with real dyno results on this forum, who can ascribe improvements specifically to the divider. Pride may silence many who note no difference.
I'm a tightwad, and proud of it. I would fit a colloidal tin fuel conditioner before a port divider - and that product has more than its share of detractors!
