Need help identifying Big block roller rocker arm

Doesn’t the HS rockers have a bigger body??? Now I have to go find a picture and see how far in the weeds I am.

I wasn't saying THIS was them. I was simply saying that Harland Sharp did make some for Mancini. It's just a guess. Since they don't have "buttfucker's rocker arms" stamped on them, that's all we can do is guess, right?
