to me a rocker arm engine is amazingly poor for an engine design , compared to a overhead cammer, an overhead cam motor is in a way the ultimate flathead, , I agree the flathead is quiet and smooth but that may be a function of lower power output, routing the wxhaust through the block probably not that big a factor as overhead valve designs do a similar thing through the head. rocker arms allow compact design but waste a lot through the valvetrain
