Are you saying you already have a cowl hood, and want to add the cowl induction air cleaner?
If so, I can give you the height of the new air cleaner from the carb seal to the top of the hood seal rubber (uncompressed) It's 1-1/16" from carb to top of air cleaner lip, and 2" for the rubber seal. That's a total of 3-1/16". The rubber can be compressed about 1-1/4".
Bottom line....the underside of the hood to the carb seal should be between 3-1/16" and 1-15/16"
If it is greater than 3-1/16, you can use the small block extension ring, and cut it to whatever you need.
If it is less than 1-15/16", find a drop air cleaner base that will work, or try to modify the stock cleaner to fit. Failing that, you would have to change the intake.
Just a caution....even a stock 163 intake may be a problem, if you do not have the correct motor mount towers.
