It will help. But also you definitely cannot always hear detonation. I consider .046 on the very edge of wide.

I'd love to have a spark-knock retard type ignition such as a J&S, not cheap but good I believe.
I'd really prefer electronic fuel injection and timing control together and run high compression much easier with better octane tolerance, but that's thousands of dollars to just replace a cheap carb & hei setup (and more time and trouble than I want to spend).
