Francesco,

A zone VIII density should be fairly dense. Of course the film (EI rating) and the developer dilution and time will all have an effect on the density. Are you planning on enlarging these negatives?, or are you planning on contact printing the negatives? If you are planning on contact printing them on Azo then the negative densities should be up around 1.45 to 1.60 above low value densities to fit on Azo grade two paper.

I would try to print the negatives to see how they print because the print is the final determiner of your process.

Please keep me informed of your results.
