I know this has been discussed a lot on here, but I wasn't able to find an answer for my question.
With aluminum heads they say you can generally raise the static compression ratio 1 point because the aluminum dissipates heat quicker.
Now when you are inputting all of your variables into a dynamic compression ratio calculator what compression ratio would you put for aluminum heads.
SO lets say your calculated compression ratio is 10:1, but you are using aluminum heads so it basically has 9:1 compression ratio.
In the dynamic compression ratio calculator do you input your calculated 10:1 ratio or your "effective" 9:1 ratio for aluminum heads?
