Default [Q] Downgrade from CM11 to rooted 4.3 rom

Hello all.

I am wanting to install a rooted 4.3 rom over top of my CM11 nightly. I just can't stand the bugs anymore. Is there anything I have to do besides flash the zip in cwm recovery and flash the firmware using Odin? And confirm this will not mess with my bootloader (ie lock it down)

Thanks a million!
