A quick summary: there is a specific subset of morphs (INJ and REM's) that live in the folder called !DAZ in the Poser libraries. If you have multiple runtimes, this folder must exist in the main runtime of the version of Poser that you use. The name may not be changed or its location moved. The V3 and M3 morphs live there. To use them, load the morphs you want i.e... "alien head", and you should see the alien head morph in the list of head attributes such as "mouth size" etc.., enter a value such as 1.0 or 0.2 or twiddle the dials as you prefer and the morph effect should happen. Daz3D has a detailed explanation on their help page. Note: each creator has an enormous amount of control over where they decide morphs are supposed to be stored so read the readme and they should tell you where the morphs live such as the file list that Daz includes in their readme.
