The correct valve clearance to use depends mostly on the shape of the initial lift ramp of your cams. If you get the clearance too small, you don't get a sharply positive valve closing, leading to small exhaust leakage and hotter valves and seats, and a similar effect on the intake side.
I had a set of ISKY cams that had very wide lobes - long dwell at full open - with really rapid open/close ramps. Lots of power, crummy fuel milage, and very small clearances. - 0.08/0.10.
