Not quite. But that's the general idea. Once cams get past a certain size though, the overlap and static Lobe Center Angle gets to the point where as much movement as VANOS or the adjuster on the MB intake cam is actually a hinderance. So you either have to modify the gross cam movement (I'm not sure if VANOS is infinitely variable or just on/off like MB) or remove it. I'm probably going to be using pretty healthy cams and pushing the powerband way up in the powerband (I can afford it, my car is 1200lbs less than the lightest W124...) and seeing how linear I can get response and power between 4k and 8500 so I'm just going to use two exhaust cams as cores to a hardface and then removing the adjuster.
