They are aftermarket pistons with valve reliefs for large intake valves probably with a high lift cam.IMHO

RE: camshaft lift

No those are regular flat tappet hydraulic lifters,in order to obtain cam lift/duration you will need to id the cam model and make,then you can get the spec sheet,it more than likely be a ford cam and have a letter stamped on the front where the cam gear mounts.
