Changing Swing Weight for 913 D2 10.5 with the Mitsubishi Bassara Reg 50H

I play a 913 D2 10.5 with the Mitsubishi Bassara Reg 50H. I have the standard Red dot weight. If I go to the heavier 11 or 14 gram weight will it change the swing weight?  I understand that the configuration is currently a D1.  Am I correct?  I am considering a heavier head weight to possibly get more distance?  I swing between 80 and 90.  Help?
