"The Modular engine, or "mod motor" as it is often referred to, is Ford Motor Company's modern overhead camshaft (OHC) V8 and V10 engine family. It gradually replaced the Windsor small-block and 385 big-block engines over several years in the mid-1990s. Contrary to popular belief, the Modular engine did not get its name from its design or sharing of certain parts among the engine family. Instead, the name was derived from a manufacturing plant protocol, "Modular", where the plant and its tooling could be changed out in a matter of hours to manufacture different versions of the engine family. [1]. It is used in Ford trucks, (called the Triton) in Lincolns (called Intech) and in Ford and Mercury cars. In 2004 (2002 in Australia) Ford introduced a 3-valve SOHC with a Variable Camshaft Timing (VCT) system."

the word modular basically means a bunch of sub assemblies are put together to make a whole item while each sub assembly can be changed without changing the whole item.
in this case, the shortblock is the roughly the same on 4.6's and the heads are different. This is why you could put 2,3,4 valve heads on 4.6 and 5.4 blocks.
