Hey all, i was about ready to put my head back together im going to take the cams outa the box and plastic wrapper, when i notice 4 spots of rust on the cams. its not on the lobes but on the part that rides on the head, any1 ever had this b4? the cams were still in box, in plastic wrap, sitting in my enclosed garage. are they still good? will they work? is this crowers fault or mine? wtf?!?!?
