After valve adjustment stall issues.

I have not yet installed it but I had a cam reground by Oregon Cams and the "cam card" sheet that came with it says to set valves at 0.012 on both I&E. seems too tight to me on exhaust.
Also every slant (but 1) that I have ever had to adjust the valves on they started out way loose. which is why the /6 has its distinctive tell tale lifter clatter/
Once adjusted to spec (0.010/0.020") they are quiet. so I'm sure that a few thou loose, won't hurt a thing.
