The 2-3 shift is almost always higher than the 1-2. This is why A&A sells a shift point corrector spring kit. They have two springs that you can experiment with for the 1-2 shift valve so you can match the shift points. With this, and their 5600 or 5800 (or whatever rpm you want, they have a full range) governor weight you can build a transmission that will shift both 1-2 and 2-3 at whatever rpm you want at wide open throttle. With normal driving at part throttle the shift points are slightly elevated.
