The new heads use 2 intake 1 exhaust. Ford calls the new valve timing system Dual Equal Variable Cam Timing. It is a hydraulically actuated system that simply changes the phasing of the SOHC shaft to the crank. 50 degrees of total variation. There is no control of individual valves. The Ford literature I have says it controls timing in varying amounts in the midrange and WOT. Timing is retarded at WOT. Its suppose to be the same system as on 5.4 Triton. As a matter of fact, I believe the two heads (Triton & Mustang) are very similar to each other. This ability to control cam phasing is also used for emission purposes. Apparently it has allowed Ford to skip EGR and air injection on this engine. If I remember correctly, on the 2.0 Zetec engine a few years ago, which had variable cam phasing of the exhaust cam, the EGR was deleted. Deletion of EGR system on that engine basically paid for the VCT hardware. Although individual valve control is not used, ala VTEC etc, the heads now incorporate (some lit has said these valves are in a spacer between the intake and head) something called charge motion control valves that try to simulate two different sized intake ports. I'd like to see more detail on these, or photos. It sounds like another version of the intake control on the 96-98 Cobra, but maybe not. About valve control, don't know if thats continuous or discrete steps. Even if it was stepped there would so many ways, especially with the engine now having throttle by wire, to mask the changes I'd guess you could get a pretty smooth torque curve. Probably no surge like that felt on a 96-98 Cobra when the intake control valves open at around 3,300 RPM.
