We Run the Trick Flow and im happy with it.
From the fwiw/opinion department : On our "type" engines, i would stay away from port style injection and use the Sniper or other carb flange type injection for the simple reason of intake air density .
You don't get any intake cooling with injectors below the air intake .
With the carb flange mounting EFI units , you do get that intake /air cooling and thus air densities are higher, air flow inproved.
There are dyno session papers and videos online to gather data from.

Hope this helps.
