Yes, you have to replace both, the gaskets and screw grommets to have a durable work done. I used FELPRO brand and is still holding good after 50K+ miles.
When you replace the gaskets, clear the surface of the head and gasket. Then apply a thin layer of new oil to the gasket as you install the covers back on.
