That would be a DOHC (dual overhead camshaft) engine. Commonly used in European and Japanese engines, becoming more frequently used in US-made engines. The Mustang Cobra V8 engine has been DOHC since 1996. There are also SOHC (single overhead camshaft) engines.... again the Mustang V8 (non-Cobra) has been SOHC since 1996.

The SBC is one of the last holdouts using pushrod operated valves for high performance engines. Most people who don't understand consider the LSx family of engines "outdated" because they still rely on the pushrod design. Of course most of those people are looking at the rear bumper of the LSx vehicles, as the leave them in the dust.

They aren't exactly 'in the heads'.... they sit on top of the heads.
