Valve noise with synthetic

I must admit that I am disappointed. After much debate and indecision over which oil to use, I finally decided to go with synthetic oil. Cost was never a point, just like wine, if it costs more it must be better, but I do have more valve noise at idle. I debated over going with 15W40 dino or 15W50 synthetic and synthetic won out, but I am not sure if I can handle the additional valve clicking. IS this normal with synthetics, even at the same or higher viscosity? The motor is a 560 with 53,000 miles.

I hope not to start a oil debate, but I am very curious as to the explanation.
