    The vendor gives no information as to the combustion chamber "cc" size. or what cylinder diameter is is designed for.
    It is particularly important to know the volume of the combustion chamber to work out the compression ratio.

    Where is information describing the combustion chamber volume?

    From what i can see, the design is a straight copy of the CR Machine Manufacturing billet cylinder head, but what version?
