I just wanted to respond to this dead post. It was indeed a lifter. One of the rollers wore to **** and had play in it. Once i replaced the lifter and cam all went back to normal.

Glad to hear it and the fact that you let us know the fix. Still sucks that you had to tear down the top end of a new motor. What lifters and cam was it?
