The Head scan was downloaded here https://www.3dscanstore.com/blog/Free-3D-Head-Model. 3Dscanstore has a lot of other high quality amazing models too that are work checking.
So I have directly converted from FBX to Cinema + CentiLeo and played a little bit with the textures. Actually there was an interesting "Cavity" texture in the package that was used as displacement map and not as bump. But the bump map slot was also used for some additional detail coming from normal map.
With Displacement Map the look of Zoom-In, glossy highlights and subsurface scatter effect is much better than with just Bump. However, displacement map produce 100M extra micro-polygons, but they are efficient.
Render times are 5-10 min on the single old and small and slow GTX 970. Or 1:30-3min with two of GTX 1070. 2K by 2K image resoultion
