There's no real rule for setback as every boat is different, but you are able to raise the motor up higher than the given bolt holes. It's a testing situation more than anything. Keep moving the motor up until you lose handling on moderate turns. Be prepared to trim down in corners as that is a good thing for carving a nice turn. If you are too high or trimmed out, the prop will blow out and let loose.
One thing to be careful of though, when you go past the normal bolt holes....
With a setback or jackplate, you can potentially raise the motor high enough that you lose water pressure to your cooling system and that would be a bad thing. If you have a pressure gauge, you can monitor what is happening. I'm thinking you could try setting your anti-ventilation plate 2" above the lowest point on the boat as a start. Solas should have a steel line as well. I think michigan propeller might have something as well. I'll do a little searching to see what I can find as well.
