draft issue, anybody have a suggestion for a better way

I have an issue with the draft (draft 5 & 6) on two faces in the attached model.  It is basically results from the non-symmetry about the mold parting line (and most probably more due to my modeling technique).  But does anybody have any suggestion on how to do this differently.  The basic problem is that due to the difference in length of the two drafted faces the amount of material added is different resulting in a step at the parting line.

TIA
