I don't know anything about the 196 ohv engine but from what people have said the intake valve is in the head and the exhaust is in the block, is that right? In the 1950's I did some work on flat head Fords and we would port and relieve the block for better breathing. Wouldn't the same procedure work on this engine? It sure helped the flat head Fords to breathe better and you could run a hotter cam. Just a thought. _______________________________________________ AMC-List mailing list AMC-List@xxxxxxxxxxxx http://www.amc-list.com/mailman/listinfo/amc-list or go to http://www.amc-list.com
