    the pistons are different because thats how you change the compression.

    Most of our heads have the same combustion chamber size. Except when you have them milled of course.

    n/a are 9.4:1

    s/c are 8.5:1

    The wrist pins are also smaller on a N/A piston compared to a S/C piston. They're not interchangeable with rods.
