It seems the more I read, the less I am confident with adb, flashing, backups etc.... :S
If want the stock kernel download the factory images from google and flash the boot.img via fastboot. That's the easiest way.
If you still want to use nandroid backup then copy the nandroid backup to the correct location... Head over to Philz Touch recovery and use the custom restore option by which you can select only the "boot" and "system" partition. But I haven't tried doing it so can't say whether it will work or not. However, technically it should work. I have no idea how to do this using TWRP though as I haven't used it much.
