Spark Knock Fix

I have a 10.75:1 Compression 355 Chevy with Vortec heads. I currently use 94 octane gas with no octane booster. The car seems to knock at around 5300 rpm. What could be a solution for this. I retarded the initial timing, richened the carb slightly, knocking is a little less bad. I was thinking about colder plugs and or maybe limiting mechanical advance. Could octane booster help?? I yes, which brands are recommended.
