head studs

[Lizirbydavis@cs.com]

Is it prudent to replace the head studs when rebuilding?  Is there a way to 
tell if the present hardware is deficient?  Is it worthwhile to buy the 
"upgraded" studs?  APT sells the set for $129.00, Moss is $159.00. I did buy 
new 
fasteners for the mains and con-rods.  The bolts from Moss have a flange (like 
a 
washer).  The old hardware does not. Why are there no lock washers on main cap 
and rod bolts?  Should I use locktite?
