Don't do semi-stand. Do Kodak agitation method every 30 sec or use continuous agitation.
If you are doing studio portrait like George Hurrell's classic headshots, it has a lot to do with lighting as well. Many portrait photographers today are not bold enough to use specular lights like his era. Put your softbox and shoot-thru's and switch to shiney metallic parabolic reflectors, especially the hair light. Be careful about the lens flare, especially if you use vintage lens. Any straight line film would be made to look reasonably darker midtone and harsh highlight like this... If the skin comes out too shiney/dewey use water based airbrush makeup and/or mattifying gel on the skin.
