I have the act streetlite flywheel and oem clutch and it is pretty loud off throttle. My wife actually gave the the "OMG WTF is that noise" the first time she heard it. It is normal. It sounds like all sorts of hell is going on.
I don't think you could have been rougher separating the tranny from the motor than I was. Slide hammer/5 pound maul/3 foot prybar.
