Those pistons are not OE, they are OE replacements, which basically means they are Sealed Power without the coatings which is what Ford sold after production ended. Notice the F6xx part number which obviously is a part number that was generated after SC production had ended. Price is ok, but nothing to get excited about, the Sealed Power versions come with coated skirts already, so +1 for Sealed Power.
{Edit} The true OE pistons were also hyperutectic but were a stronger design. All aftermarket hyperutectic pistons regardless of the name on the box (and yes these "OE" pistons listed above are aftermarket) have an inherent design flaw that makes them significantly weaker than stock and subject to skirt failures under detonation (more common than you think). Just FYI.
