What do you call bricks laid flat across the wall with the ends showing to the face of the wall?

The term for bricks laid flat across the wall with the ends showing to the face of the wall is "headers." Headers are oriented such that their short ends are visible, and this placement often serves structural purposes, such as providing support in the wall or spanning openings. Each header brick contributes to the overall strength and stability of the wall by distributing loads across a broader area.

This technique contrasts with others such as stretchers, which are laid long-side facing out, or rowlocks, which are laid on their side with the end visible. Blocks would refer more generally to larger masonry units, such as concrete blocks, rather than specifically this type of brick arrangement. Understanding the function and orientation of headers in masonry is essential for constructing sturdy walls that meet structural requirements.
