John, my radiators sit at an angle between 3" and 6" from
the inlet. Needless to say a bit on the short side for a diffuser.
My duct inlets are a integral part of my fiberglass diffuser duct, so I did not
use any silicone (or any other connecting material). However, putting the
radiators back a bit further and using a silicone or other smooth (some folks
have used diving suit material of some kind) material to minimize the transition
from inlet to duct would be a smart way to go.
Others may have some more useful suggestions
Ed

Ed, how much distance did you use between the
cowl and the radiator diffusers. Also did you install a silicone belting
cuff on the joint. JohnD
