It should be, but why do you need to flash a stock recovery? Only use boot.img from your nandroid. Nothing else. Make sure you wipe everything via CWM EXCEPT the SD card. Suggest you copy the clockworkmod folder to your PC FIRST just in case - this will make it easier to copy the boot image to the fastboot folder anyway.
