Ah, The proverbial can of worms. The use of 194 heads has been discussed here quite a bit over the years and never seems to come to a conclusion that we all agree on. There are several old threads here on the subject but searches are not very easy. I'll post a link to one about a truck engine I still haven't finished yet. (usual for me) This is a 292 low rpm truck engine build not a race engine but there is some basic 194 head info that may be of interest to you.It starts out about cam choice but gets to heads soon.

The easy answer to your question is you could expect from 1/2 to one point compression gain. So 9 to 9.5 to 1.
