Do you mean WHAT octane should you use?

Your compression ration is a bit higher than that.

Standard= 13.17
.25 Oversized= 13.23, roughly

I would'nt use anything less than 93. Make sure you have a really good tune.

the lowest octane the doesnt cause detonation.

Starting this thing up without a wideband and ready to tune would be a foolish mistake, running a generic base map to break it in would be another. Tow it to a dyno.
