I'm not sure why I would have to mill at all. According to the calculator provided above, I would be as you pointed out earlier at 9:1 compression ratio and not 9.5:1. The #64 heads will provide me everything I believe I need for around $1200 after the rebuild is complete. As I stated in my initial post, I want to be between 300-350HP after the build and be able to run on pump fuel. I believe the #64s will get me over the 300HP with the right cam without milling. I'm currently at 220HP with my 1974 heads.
I would love to buy the Eddy's but do not have $2400 to drop on heads. Please verify my information above and recommend a cam which would add horsepower to a daily driver.
