I don't know for certain on the duration, however, I can verify that according to the TSRM, NA cams 
should have slightly less lift than turbo cams.

One differece seems to be in cam TIMING though, with the alignment marks properly set, I seem to 
remember the cam timing was altered from the turbo to the NA cams, which was responsible for a 
moderate increase in midrange power on the turbo engine.  There was some speculation that the NA cams 
might have increased duration on the intake cam, but nobody ever came forward with substantial proof.

Note that the exhaust cam should be identical for both GE and GTE models of the 7M.
