    Markings on pistons (dimples?)

    I got a used short block and 2 pistons have dimples on the top in line with the valve reliefs. Can anyone tell me what this means?
    Thanks,
    Guy

    Re: Markings on pistons (dimples?)

    I couldn't get the camera to work.
    When I looked on the underside of the pistons I see a pentastar with the following number, 4105491 but no Mahle anywhere.
    The other 2 pistons have the same number 4105491 and Mahle on the underside.

    Would Silv-o-lite Hypereutectic pistons have a Mopar Pentastar on them?

    Thanks,
    Guy
