Quote - Can someone tell me where I can pick up V4 head and body morph to make characters with, because all I seem to find is V4.1 head and body morph.

Thank you!

They're just morph targets, and they'll be included with the rest of the V4/4.1 stuff, in your download page at DAZ. If you mean within Poser itself, much of that is in the Body selection. "Characters" are largely predefined full body morphs, although the head, for example, has its own, independent from the rest.
There is nothing added to aid in making characters with aside from that, as far as I know.
