Throttle kickdown, Should I cut this off?

Flat base air cleaner OR get the air cleaner adaptor ring set from local parts store for around $10.00 to raise base 1/2". That is what I did. I had to take my rod from the bellcrank to the carb heat in vise and bend it the opposite way for the correct geometry. I had to also weld the slot some on mine, so that I could get full kickdown at full throttle.
