I'm afraid Oriental VC papers are not available here in the UK so we have not been able to test them. However, if you can give me the figures from the manufacturer's data sheet for paper speed (ISO(P)) and contrast (ISO(R)) I can suggest a starting point.
It is always best to do your own calibrations though because your enlarger, chemicals, working methods etc may all be different to ours.
I suggest you use the dual Y+M filter settings we've included on our website if you are using the colour head and not under-lens filters.
Hope that helps
