One thing to note, NSFW has avcs, while the OP doesnt. I am sure this will have an effect on lower rpm timing, but even at redline OP's timing is high.
I run 92 octane, but I'm still on a stock longblock. I could probably afford to run another degree or three, but I don't want to push it.
AVCS is 25 degrees at 2400, tapering to 0 degrees at 4800.
The latest tables seem pretty reasonable. I'd subtract 2 degrees across the board, do a couple pulls, verify it's not knocking, then try the tables shown. Then again, with your forged pistons, you can probably afford to be less cautious then me.
