It's your car so do what you want. In my opinion it's kinda silly to go through all that trouble when a 3/8" spacer will likely cure your ills.
Problem with that is the hood clearance with a stock air cleaner which he is choosing to use.
But I guess the question is what air cleaner is he using ? If it's the stock unslienced then a 13" Ford Motorsport open element base will work with it and drop the air cleaner top down.
But then there is the issue of the carb he is using
