See where surfaces cut into the cyli, mark vertices match nearly the 16 sided geometry select them and select either "move to nearest edge" or "surface" this will adapt the shape to the head

I often do the same, but with hi-res prims. 
Select the vertices inside the cyli/headshape and use the Scale tool to resize/move in the xz-plane with the Manipulator placed in origo.
