Just noticed it when installing an intake the bolt next to it was loose as well and I screwed that in tight. Its solid and doesn't have any fluids on it. Just a solid goop piece.

Just some silicone that squeezed out when the valve cover was installed. Don't worry about it, just leave it.
We still use dabs of silicone where a gasket has to go over a break between two metal surfaces - here it's the head and the timing cover.
