I'd try adding half a degree of ignition advance across the power band in the high load areas since your log loos to be relatively knock free, then go from there. Take a log with the increased ignition advance trim back timing in areas where you are registering knock corrections or add more advance if you think it can handle more.
Personally I've seen notable increase in whp by increasing ignition timing only .3* to.7* in the right spots on the powerband. Though I'm not sure whether if your butt dyno is going to feel a 5-10whp increase at the top end, to be honest.
