These are the numbers I measured on both cams:

MM305 S: 305º/320º@.020", 279º/287º@.050", 197º/200º@.200", 143º/143º@.300", 112º/107º@.350", 0.433"/0.420"
324/324: 324º/324º@.020", 290º/290º@.050", 200º/200º@.200", 145º/145º@.300", 112º/112º@.350", 0.433"/0.433"

The new MM305 S cam has a more aggressive intake lobe, with less duration at 0.050" but the about the same at 0.200" lobe lift.
The exhaust lobe is not as aggressive as the intake, very similar to the old 324/324; perhaps more stable from a valve float perspective.
