They will have lower internal capacitance to ground with the shield removed so the might have a better high end. But more likely to pick up more Hum and noise with the shield removed.
 

 
I haven't experienced any issues thus far.  The C3g I stripped are quiet and noise/hum free.  The only noise I have ever heard inside the headphones has been from misbehaving 45 tubes.  One of my Sylvanias likes to make what I can only describe as farting sounds.

Btw, David, congrats on your listening room.  Very impressive.  Hurts to look at it a little bit I must say.  As an apartment dweller I can't do the things with speakers I really want to do.
 
You need a sexier name for the 300B than GAPE though.  If I dare say so I think I did a better job naming my 45 amp.

Nice to know, how difficult to remove the shield?

It's tedious, but not all that difficult.  Trickiest part is finding something with a thin enough edge to wedge between the seam where the aluminum joins together.  I used a pocket knife blade.  The glass does not make physical contact with the shield so there is not nearly as much danger of breaking the glass as you might initially think.  When the two halves of the shield finally pop apart after all the prying it finally makes sense.

Shield removal~
 
Send Yamamoto-san an email inquiry. He replies quite quickly. He routinely removes the shield for his Siemens C3m tubes...

That said, it was Dave's unbelievable speaker stereo which was the real treat. Very few have ever heard music reproduced in their home this well. It was astonishing.

 

really nice amplifier
