I know its worrysome but try to not obscess over this fact of life with any new engine. The first 3-4 oil changes every couple of hundred miles you will see shiny stuff suspended in the oil. If it starts easiely, runs and with good oil pressure you are very lucky the machinest knew enough to put the cam bearings in correctly.
