Don't cut up your hood scoop,make a Air pan out of sheet metal or Aluminum,if you have 2-3 inches clearance from top of carb to bottom of scoop you can run a 2" down flow air filter,put (FLAME-RETARDANT Foam) across front,both dides of air pan so when hood is closed you have a good seal.If your hood just has a hole cut out for Carb,use 4 pieces of foam make a square.A down flow air filter runs $93.00 and up but still cheaper than a new hood or new scoop.
