We did some pretty extensive dyno testing several years ago and found the 194 head made less power and torque than a comparably prepped open chamber head in every test that was performed. Sages for decades have claimed miracles by using the 194 head, but professional head porters and engine builder like Kay Sissell mentioned in his own catalog that "a 194 head only belongs on a 194 engine because of severe shrouding that can't be corrected!" I'm not saying Yea or Nay, just pointing to the evidence and research that is out there, so you can draw your own conclusions.
