I'm using the alpha height map for parallax mapping which is quite subtle, you use the 'BumpOffset' node in the Unreal material editor.
The gloss map is there to drive what is and isn't reflective and also if it is, the strength of the reflection. So I multiply the gloss map to my cubemap setup to achieve this. (I wanted my front part of my turbine to be reflective whilst the back end to be quite mat)
