just having a read through the 'engine strengh' thread and can anyone clarify this, its been floating around the forum for ages that the ss head has bigger ports which is not true however in this thread amy posted
"the face of the ports are around the same size, all the manifolds I have seen have the same sized ports, so there would be no gain in enlarging this area, however the port down through the throat and into the bowl is larger. i'm really curious to find out more about this as i'm sure that Nissan would have made these changes for a reason."
can anyone confirm this just think it would be usefull to clarify the exact differences between the k10 heads.
