Thor, I'm fixin' to sound like I know what I'm talking about -- I don't.
That said:  The EGO is supposed to be fast enough to respond to each
pulse from each cylinder -- hence FOMOCO's SFI.  My old town car
had SFI and used an EGO in each exhaust manifold.  According to the
Ford book on emissions devices (don't know the name -- get it
at the part$ house), it samples the mixture from each cylinder
and adjusts same to achieve optimum fuel distribution.
