Horsepower, compression ratio, airflow?

Sounds like nobody knows, doesn't it? Alright, an increase from 8.5:1 compression to 9.5:1 compression or 10 cfm all across the board. This means 10 cfm increase at .100" lift all the way to .500" lift, or an increase from 8.5:1 to 9.5:1. Which will give a greater average horsepower increase?

Did anyone really think I was talking about 1:1 or 100:1?
