How much would these heads drop my cr?

Right now with 64 cc heads I'm running 10.1 CR but as this car is no longer going to be my daily driver i wanna get a little crazy with it.. how low could i get my comp ratio with some 76cc heads? im thinking AFR's or something if they makem in 76cc or around there and I'm gonna wanna run some boost... how high will my comp ratio be?

Assuming you have a true 10:1 CR with 64cc heads, switching to 76cc will drop it to 8.8
