Did I wipe a lobe or ???

I was just having a conversation with an engine builder the other day about 440 source offshore heads pushrods hitting. I was talking about the offshore small block heads and he went right to those 440 heads. I won't even go in to the disasters in the dyno room that he mentioned but by the time I got off the phone I was pretty convinced if I'm going to try and use offshore heads not to contact him about it.
