Guys,
I don't know what you consider to be "heavy," but back in the very late 80's, Beau Matlock, while at Diamond Gym used 85 pound dumbells for lateral raises. Before you guys go off, I actually saw him do a clean 8 reps for a couple of sets. It was most impressive. Before that, I had only seen a guy named Kurt from Westside Muscle in Rutherford use 65 pounders for good reps.
