In the old days, there were knuckleheads, panheads and shovelheads. Our shop just called them Shovelheads. Period. Or maybe a generator shovelhead? Now I get corrected if I call dude's shovelhead (" A Shovelhead") instead of a "Cone Shovel." What the hell? I want to say, "Look you skinny little turd shithead - it's a freakin' Shovelhead - or better yet "A troublehead" and you probably couldn't even set the valves on the thing. I don't know why it bugs me, but it does obviously. One day a guy was telling me about his Ironhead Sportster (and he called that a Shovelhead Sportster) and I know what he meant, and it didn't matter, 'cause some old timers call them Shovelhead Sportsters since they were actually alive when Harley-Davidson went from the flathead K-Model - to the Shovelhead Sportster overhead valve (which just may be the first actually named Shovelhead?) and not the Shovelhead the shit-kid calls a Conehead. So take that, shit-kid !
