can head bolts be "tightened" mid-use?

[abatzis2@hotmail.com (Michael Abatzis)]

well, with standard bolts you can't really do that since they aren't torqued 
to a value. it's 1/2 turn past 60 nm or whatever, so i don't know how you'd 
spec it.  not to mention they alledgedly stretch, though i've reused them 
w/o difficulty and other listers have measured them before and after and 
seen no stretch. head studs you can retorque. oh, and the bolts won't loosen 
just sitting there anyway. imho, you're more likely to warp a head/strip 
something by tightening more than fix something.
