Distance from Air Filter Above Carb to Carb Top??

If you have motor trend TV or plus, checkout the engine masters aircleaner test. Simplified, down flow is better than across flow. Velocity stacks with a filter actually made horsepower verses no filter at all. And so did a salad bowl with a k&n filter lid.
Edit: the really short filters, like the flys eye filters were power killers. And they don't filter very well either.
