Default Aluminum and copper

Quick question, in a nutshell… Is it okay to run copper header gaskets on my shiny new round port aluminum heads?
I think it must be okay since copper cylinder head gaskets are readily available, unless they’re only used with cast iron heads.

I seem to vaguely recall some science class jazz about anodes, cathodes and electrolytes and one of the metals slowly “dissolving” (more like pitting) the other. Also remember hearing something about it as more of a maritime concern that boaters talked about. And we all know boaters are largely belligerent drunks anyway, haha.
