I think you mean stamped steel rockers, but anyways you are probably hearing pinging. The rockers should be quiet unless they're loose, then you would hear the noise all the time, not just under load. I had an 86 that would not take more than 12-13 degrees no matter what. Some engines just react differently than others.
