Another thing that could be causing your engine to not take alot of spark could be hot spots in the combustion chambers or hot spots on the piston faces. Have you tried using a colder plug?

I had considered alcohol injection, but on an NA motor that seems pretty gay. Cometic has a specific model for lowering comp by almost a full point on an LS motor. At least that's what I've heard.
