One way I check to see if I have the valve clearance adjusted too tight or 
loose is using a  "go, no-go" method.  Lets say you have just set the 
clearance at .006 inch.  Take your .007 feeler gauge and try to slip it 
through the gap. If it slides through without forcing it, you are too 
loose. If it doesn't slide through, then you know you are not on the loose 
side.
Then take your .005 inch feeler gauge.  Try to slide it through.  If it 
doesn't slide through easily, the gap is too tight.  If it slides through 
easily, then the gap is set right.  Or in other words, if your .007 feeler 
gauge is a "no-go" and your .005 feeler gauge is a "go", then you have it 
set right. HTH.
