I've been using the Quick Fuel air bells on all my scoop installations for my customers cars
$32 from Jegs @ racer price.
The bell definatly makes a difference in straightning out air flow into the carb.
Last year I did several back to back tests on my Vette when trying new scoop's on the car.
the immediately noticable benefit for me was a solid 3/4 mph improvement on back to back testing with the same scoop.
The less noticable, except on the data recorder ,but more beneficial effect was the tightening of O2 variations from cyl to cyl.
Between a modern scoop design ,the air bell and better tray design,I picked up nearly 2 mph.
