The picture is taken from the passenger side so you can clearly see that they were not installing 421 SD heads on the engine, (or in these photos) BUT, you also can clearly see the "Pyramid" on the block of the 421 engine.
The block in your attached article is also straight across (on the passenger side) at the gasket surface at the front of the block, another clue of a 421 engine. A 389 engine has a cast in pocket in that area.
