Loctite?

[<rtriplett@bjservices.com> (Richard Triplett)]

This discussion on using Loctite for lubrication, accurate torqueing, and 
thread locking got me wondering, can it be used on head bolts?  I put mine 
together dry, but using a thread sealer may keep the bolts from needing 
re-tightening periodically.  Another question along the same lines, can the 
head nuts be loosened and sealed, then re-tightened one at a time without 
danger of warping the head?  
Just wondering,
