It sure is a 194 head.
One of the 194 heads I have, the exhaust ports were not completely divided to the mating surface.
Not sure if it make s a big difference, I just did not like that design.
I would use the 194 head to bump up the compression some, or else purchase pricey aftermarket pistons to get whatever compression ratio you want & use a larger chamber head.
Not sure what you are looking to do as far as a build goes?
