Wait a minute — head and header?

Yes, there are "head" and "header" elements.

They are different!

head

Used in all HTML documents as part of the essential HTML document structure. head contains information for your browser about the web page. Not for human consumption!

header

Used to group or define introductory portion of a web page, which is often consistent throughout the site. Header typically contains visual site title, navigation, etc. For web page content, think header, main, footer!
