If you are removing the spacer (carb to intake spacer?) then yes, you may need to file a bit of material for the linkage to work without interference.

As for air cleaner/filter, how can you fit a 12" air filter into the turkey pan?

Finally, K&N does not need to custom make a filter for your setup, they offer most 12-14" filters in 1/4 and 1/2" height increments as a stock item...Now, finding someone who stocks it, or is willing to order it for you, is a whole other story.
