Whats the max Dynamic compression ratio that will run on 87 octain fuel?

So I will just have to guess how to up my cranking compression up to 180psi.
right now its like 160psi/7:1DCR (8.5:1scr with a 62*IVC)
9.4:1scr with .040 quench and the same cam. should run on 87 octian. (72cc fastburn chambers)
running on the low end of the coolant heat range.
