high rpm engine clatter

I recently picked up a later year 88 turbo with a bad head gasket. Replaced as per Bently. Has 280 "new miles" on it. It runs decent. but i notice a high end shatter at about 3500 rpms specifically in 3rd and 4th gear and sometimes in 2nd when going up hill. Is this a turbo related clatter?( to my imagination it sounds like the turbine hitting the housing, but this is my first turbo so I'm not sure how they usually fail), it happens when guage gets half into yellow and thats as far as it ever gets! the timing is at 16, plugs are gapped properly, new cap, new rotor etc etc.... if I'm stationary in neutral no noise occurs at any rpm. Any help would be very appreciated. thanks..
