broken pin on rocker-arm need help

upon closer inspection, the piece laying on arm in picture in the center part of the roller pin, the outside part that rides on spring was ontop of head also! Will replace push-rod and rocker-arm then fire her up and hope I didnt bend a valve since I was under 5k rpms when this happened. And there is NO brass anything dont know what I was seeing, maybe shinny metal covering in golden brown oil making me think it was brass
