Stage II head question

[DDot690]

Are the aluminum stage II head combustion chamber cc the same as a stock head, 46cc I believe. The reason I ask is I have a stage II off center and aluminum heads I haven't had assembled but had all block work done and purchased pistons. I believe the compression was suppose to be 8.5 or 9.0 with the stage II head. I believe I will use aluminum Champions with the motor now. Wondering if I have to get different pistons to do so?

The pistons are Ross Racing 4.020 for off center. The main reason for the champions over the Stage II is I have everthing to do the stock type set up. I think I am just going to keep the Stage motor as a spare in case I some how break the stock motor in my car for now. The motor is not assembled yet and I was curious if the pistons would work with the champions seeing I bought them for the Stage II head set-up. Thanks,
