I've always just used the measurements for Dura Ace 7600 high flange hubs and been just fine. When I've taken the dial calipers to the different Suzue's, I've found a +/- 1 mm difference here and there, but not enough to affect spoke length, even radial.
One note: I did find that they like the use of spoke head washers. You might consider those. The flanges aren't particularly thick so spoke heads get to flex a bit. Never broke a spoke on them, but extra wiggle in a build isn't good.
