IMO,
if it is a 194 CI engine, it's not a desirable engine to have.
It is worth less than a 230 or a 250, running or not, complete or apart.
It's not like you can get $1000 for a complete engine compared to a an engine with the head taken off & get only $100
You would be lucky to get a couple hundred dollars complete running.

If it has a small chamber head, then that is the only real value on the 194 engine.
I do not know how many 67 Nova's came with a 194, but I believe a standard baseline 67 Nova was the 230 engine, but like I said, I do not know or follow the production numbers of those Nova"s.
If it was a 62-63 Nova I think those were more abundant of having a 194 engine?
The most I ever paid for a complete running 250 was $20.00
The last complete 250 running engine I got 2 yrs ago I got it for free.
Most people just are happy for you to pick up that lame (in there mind) inline 6 & get it out of their sight.
