You disagree that 0.25 mm is not 0.013"? Or with Nissan's HOT clearance specification?
Yes, the COLD clearance is less than the HOT clearance. But Nissan does not recommend setting them cold. Alloy heads have a different rate of expansion that iron heads.
What I did was set them HOT, then the next morning re-checking the clearance. It was only 0.02 mm difference, not .10 mm. You are welcome to test it yourself.
0.25 mm is on the tight side. 0.35 is on the largest side -- if you go one or two thousands more clearance they start making noise. One way to double-check it is to try the next size feeler gauge and make sure it won't fit.
