I was thinking the same thing Smitty said. I'd re-torque the head and  
see of that solved the problem before I removed it. Re-torque both  
while you're at it.

Now, the question is, does a leaking head gasket have anything to do  
with the marble sound? I had a leaking head gasket once on a new  
engine, but it sounded like a squeak, not a marble rattle. But like  
your marble sound, it went away when the engine warmed up. It would be  
interesting to see if a re-torquing ends the marble sound.
