Just wondering who all has had issues with the clearance on the radiator fans with this speed daddy headers

Mine seem to be pressed almost right up against it and when it's not touching if I accelerate it does and I can feel it through the body.

My question is I plan to buy to slim fans and I was wondering if anybody knew how wide of an area I have to work with? radiator looks like about 31 inches wide so I'm thinking two 14 inch fans should work just fine... Any thoughts?
