T-Man 555 Torque Cams

I just had the T-Man 555 Torque cams installed in my 103. I'm hearing some valve train noise around 2500 RPM's. Is this normal with these cams?

With the ramps on the cams being a bit steeper the valves will close a bit faster causing you to hear the valve seating a bit more. You will also get some more noise through the throttle body.
The valve train noise is prominent when the engine is under load such as when you a cruising up hill and the noise will be less prominent when on level ground or when going downhill.
If you run fairing lowers you will hear more noise then without fairing lowers.
