bad noise when throttling up

My AC 716H supposedly had a short block put in it before I bought it (Kohler K341S.) It seems to run strong and cuts very nicely. One thing that worries me is, if it's at idle and I push the throttle forward quickly, it emits a rather loud sharp metallic sound. If I ease the throttle up very slowly, it's fine. This only happens when speeding up from idle. Any ideas?[A href='http://www.wheatfarm.com']http://www.wheatfarm.com[/a]

Don't take Bill up on that bet. My K301 made the same noise before I replaced the head gasket. My head and block were okay, but check for flatness.
