Head milling
How much can be flat milled off 400 2v heads without them cracking? This is for a race motor. Also, does anyone know how low you can run the CR for 110 octane racing fuel or alcohol and actually have it make HP and torque?

Head milling
Will I'd say you could mill them untill the indent is gone that's casted into the head between 1 and 2 cylinder's after that your on your own.I have Boss 351C heads with 62cc Chambers and .030 of an indent still left in the head and I'm running my 400 at 14.5 to 1 on 116 octane fuel.
I'd see how far I could go down But I have a 55 gal. drum of fuel to use up first.
As for Alcohol I think you can go up to 16 to 1 on that stuff.
If I'm wrong tell me on the alcohol.
