As suggested by Hotrod Lincoln I measured the distance from bottom of lifter to bottom of the pushrod depression. That distance is very close to being the same on both lifters. Question answered, thank you. Different in appearance but function the same.
Please note that "very close" is not "the same". I would strongly recommend verifying your combined lifter/pushrod length is correct before running this setup. It doesn't take a lot of error there to kill a pretty hard/expensive to replace cam.
