i know the left heat shield is lose, but this sound is when i let off the throttle, it sounds like it is coming from the middle of engine, i have a feeling it is time for valve adjustment.
Is that the only time you hear the noise - when backing off on the throttle? Improper valve adjustment will show up pretty well any time the engine is running. If you can't weld the heat shield, try clamping it with a hose clamp to at least get rid of that issue.
