How can you tell between a -2 cc and -7cc piston? and way to visibly look at them?

If you have both to measure, I'd say just use a medicine dropper and drip water on them. Count the drops and see which one takes more. With both it would be obvious looking at them. Another good way would to be call the producer and ask them.
