Interesting , thats what my victor knock offs flow at .600 .
No more than they go up from there , I`d probly not twist it up much higher , and change to a hair shorter gear , just fo grins----------
The Victor heads and copies are a good head from what I hear but I’ve slso heard nightmare stories of changes over the years making some different than others. Different rocker offsets and all kinds of issues getting them set up to run bigger cams. I personally have two sets of 440-1 heads and two sets of B1 heads so I won’t be traveling that road.
