Flashable KK Bootstack zip?

I'm going to be flashing the LP bootstack so I can run CM12.1/AOSP, but if I wanted to restore my Nand backup I will probably need the flash back to the KK bootstacks so it can boot.

If I restore a stock rooted KK nand with the LP bootstack will it still boot?
If not, where can I get a flashable .zip for the KK bootstack?
