shims... what a friggin' pain!

I just finished doing the shims on my ZR-7 a couple of weeks ago, and 
shim-under-bucket is no fun.  When I rechecked after the cams were back in 
place, most of my clearances were a little beyond the loose end of the spec. 
Since I didn't have any more of the necessary shims (13 mm diameter!!! DOH, 
can't use my massive supply of GPz shims!) I decided to just run it.  A 
loose valve is a happy valve!
