Tightening head bolts on engine stand?

[mr.utility at highstream.net (David Utley)]

Ah, but the pointer type gets out calibration because of use, not improper 
storage...  :-)  

Those pointer types get weaker and weaker with use, so therefore the more you 
use it, the likely you are to be under-torquing...

At least, this is what I have been told (by folks much smarter than I)...
