If everything is clean and FLAT it does not matter whether you use a sealant or what type sealant. I have used aluminum paint, copper coat, and nothing without problems when iron heads are installed.

Torque nuts in several even increments and DO NOT over-torque. Go through at least 3 hot-cold engine retorque cycles and drive forever.
