hey guys i was just wondering do these magnum heads have a tendancy of cracking?? I am getting my engine rebuilt and they took it apart and my heads are cracked, and my cam is scuffed along with the engine rebuild. I just heard it somewhere that these heads crack alot

 

Yes. Search up Rex's(RextheDOGG or something like that; It was better when his name was tdrex lol) re-build of his motor. His heads cracked in the valve seats.
