Generally before installing custom ROM's on 4.4.2 you need to upgrade your OS On the device.
So you need to flash a stock KK, then flash a custom recovery, then flash a custom ROM. If you tried to flash a custom ROM designed for another bootloader you'd bootloop or potentially do damage to the device.
