MGB valve adjustment

["Tyson Sherman" <tsherman@tecinfo.com>]

Hi folks.  I'm trying to adjust the valves
on my B.  I adjusted them (cold)
so that a .015" would go thru and a 
.017" wouldn't (cold) and they are
noisier than before. 
Before I had a few noisy (clatter) ones.
Now they all clatter.
What's the secret to doing this right?
How quiet should the valvetrain be?
Thanks,
Tyson Sherman
