I had a Hughes solid do that, it didnt look broke off, just a flattened angle no.7 and 2 one or 2 others-around 2002 iirr, had a mopar purple with porosity on a lobe as well, caught it during a refresh a bought another -same cam.
In the first post on that one lobe you might think there was some porosity issue, then the other lobe just looked wiped in typical fashion. It could have just have porosity issues and just looks broke off when it's just wiped and showing its shitty cast core, idk...I look at this stuff on my cell phone...so it's a guess at best mostly.
