But, Bob, Austin were using Ricardo designed heads at least seven years earlier than the late Ruby. The Ulster and the Nippy heads are both Ricardo designs. You are right about the harshness on 2 bearing engines, but I think the whole 3brg/ HC head thing was to maintain performance in the face of ever increasing weight. As an automobile designer that sounds very familiar.
