Reminds me of when I first built my Spitfire. It had a 1296 engine with
a GT6 gearbox (input shaft cut down to fit), an aluminum flywheel and a
1500 clutch and pressure plate.
After a lot of tranny pulling, hand wringing, hair pulling and angst, I
finally was able to see some marks on the sides of the hole in the
center of the flywheel where the shaft passed through and into the pilot
bushing.
The problem turned out to be that there was too little clearance to
allow the fatter shaft to rotate without rubbing. A little chamfering
of the hole solved the problem.
As it turned out, the noise sounded much worse than it actually was.

Subject: mystery noise
After I put in a new clutch and throw-out bearing and put the
transmission
back in, I end up with a mystery noise.
When I push the clutch pedal in, it sounds normal. When I put the
transmission in gear and it sounds normal. When I let the clutch out, it
growls with a metal to metal sound until the clutch is fully engaged.
Then
the noise goes away. When I drive it around the block, it works just
fine
I have taken the Transmission back out and everything looks normal.
The throw-out bearing is correct on the sleeve (convex face to the
clutch)
and the brass bushing is behind the flywheel.
Any ideas?
Can it be clutch alignment?
