You can rest easy. I am reliably informed by Omex that there is enough space for throttle bodies under the standard hood for the Duratec 2.0. The Omex kit that is already being offered fitted by Williams (see ad in the latest MOG) includes a foam filter that fits over the inlet trumpets. It gets close to the hood at the front but not too close.
I re read the original post and I don't know if that is the same for the 2.0 Zetec the position may be different. I would suggest calling Williams and asking them.
