Monxdified, iHackers and all stock based roms don't need a custom kernel (that's why you don't need to be bootloader unlocked to use them)
Just go into your recovery flash the zip. After the zip is flashed you will get an option to clear dalvik and cache.
It is always recommended to do a factory reset before flashing a custom rom, as it might misbehave. You can however try it without factory reset and then if you see that it doesn't work properly just do a factory reset and flash the rom zip again.
