Your just going to have to make sure you are listening for detonation, (ticking coming from the engine) then get the hell out of it. Have you run it really hard the way it is? Use as high an octane fuel as you can and add a few bottles of octane boost just to help out. I use Lucas Oil BOOSTER octane boost. Seems to work good for me. My air/fuel is a lot lower than that, 10.5ish above 5000rpm, fat as Rosie O'Donell.
