Just because someone told you that doesn't mean it's true. I ordered a set of pistons from CP waited six weeks opened the box and they had forgotten to laser etch the part number on the top of the pistons. I called them and they said send them back as they wouldn't pass tech with out the part number. They took care of the shipping both ways and yes they're legal.
