Hydraulic throwout bearing questions

Hey all, I’m converting my 72 duster to a 4 speed from a 727. It’s a small block car and it’s going to have long tube headers (tti) I’m a while away from installing all of it but I’m trying to stock pile parts so hopefully when the time comes I’m not scrambling around to get parts. My question is I was looking at the hydraulic throw out bearing set up from American power train instead of the z bar and the mechanical linkage with the headers and all being in the way. Is this a better setup to go with then trying to source all the mechanical linkage parts? Any advise is appreciated. Thanks!
