Blender ShrinkWrap HEADSHAPE ADJUSTMENT - Best Method?

After you make body adjustments using ShrinkWrap in Blender, is there a good method to adjusting the headshape Vertex Group to smoothly match the rest of the updated body?

For instance, I'm working on Kevin Willis--2k gave him the scrawny body type and I've ShrinkWrapped the body to be more like the large, cut David Robinson body. Now Kevin Willis' head & neck is sunk in and separated from his new massive shoulders. Is there a quicker method to get the Head & Shoulders matched up with his new muscle body--or do you just have to painstakingly & manually match the vertexes up? Huge thanks, in advance, to anyone who can help!

Yeah you have to manually edit it. Use sculpt mode for more options when it comes to editing vertexes. You can get it done much faster that way.
