At the risk of pouring gasoline on a fire...
Would putting 3v heads on a 5.4 be a viable package? Would it make for a narrower motor than a 5.4 4v? It would take some work to get it running right, but if I remember what I read in the Mustang mags when the 3vs came out, the flow almost as much air as the 4vs. Bolt a pair of these onto a 5.4, and even if you lock out the cam phasers, you should still have enough airflow to put those extra 50 cubic inches to work.
Just a thought from a longtime member of the "There's no replacement for displacement" club.
