Reuse of head bolts ...

["Buchholz, Steven" <Steven.Buchholz@kla-tencor.com>]

I thought I'd post a request for experience/opinions here ... 

It looks like I'll be bolting a head on my WX temporarily so that I can have
the car ready for Laguna Seca while the upgraded replacement is prepared.  I
have always replaced head bolts even though Bentley says that they can be
reused once.  Since I know the bolts that are there have only been used once
(as I installed them) and since I know this is a temporary situation I'm
thinking that I will reuse the bolts that I have.  Has anyone done this in
the past and had good or bad experience to share?  TIA!

I probably should consider Raceware studs when I do the upgrade ... but my
concern is a lack of knowledge of the proper way to install and tighten
them.  They are not "stretch" bolts like the factory ones.  Does anyone
_know_ the proper procedure for use of the Raceware studs in an Audi turbo
head?  I assume that you have to check the torque on them some time after
the engine has been run, how many miles/hours?  TIA again!
