Bad noise when clutch is disengaged! Help

Well we put a new throwout bearing in. lightly greased the input shaft with ams oil syn. grease. We bolted the trans back up and fired the car while still on the ramps and stands, One float was sticking spewing some fuel so we ran it just long enough to push the clutch in a couple of times, Yippee no noise! shut it off, installed shifter linkage, trans. crossmember, driveshaft, yadda yadda, go to fire it up and test drive and guess what? It's screaming just like before!!!!!!! I am about done!!!!!! The zbar is not perfectly straight so the adjustment rod is angled some, but this was they way it was before for 700 plus miles (before the noise started). I can't believe I got a bad, brand new Centerforce T.O. bearing. The old T.O. bearing with about 700 miles on it, did have a little slop, (movement forward and back) in it. What do you think?
