Ok, I have a SCB and i am tryin to figure out what the hell the heads are. I am use to seeing the symbold on the side of the heads. The ones I have seen most are the double hump symbols. But I havent seen the symbol that are on my heads before. I do not have a picture of it, or i would post it. But i can describe it as best i can. Basicaly it looks like a M but it doesnt come down to a point in the middle, it dips.
