    hard to tell from the angle, but does yours have a notch in the lip on the far end? looks like my pistons have a notch in the lip on the Ford facing side.

    yep.
    fun fact: there are 3 different types of pistons in this engine. all are the same height, same dish CC, same everything, but some have that ring around the center nub, others dont. I think when it was previously re-ringed, they were replaced for some reason or another.
