All that was with giants air volute/bell on to keep headers heat out of intake, it poses no restriction, your fa looks like it poses no restriction either but i will test it too.

He still does carbs and after testing his 4150 against 3 other carbs i am starting to believe hes pretty dam good.

I have nothing to do with his carburetor business and am not even going to run carbs on my boat but heres a link to the guy if you want to talk to him or send him a carb to be evaluated etc :

Keep in mind, hes not cheap but damn good, Smitty
