Interesting thread. I'd always heard it was gospel that when you
overhauled an engine you used new head studs/bolts. But, when I last had
my BJ8 overhauled few years ago the mechanic, a very meticulous Kiwi at
a local speed shop--who also happened to be a licensed aircraft
mechanic--reused the ones in the engine which, AFAIK, were original (the
car had about 200K miles). It's run great for going on 7K miles.
I had a Payen top end gasket set I'd bought years ago and used its head
gasket. I've heard some scuttlebutt about Payen no longer being made in
England, but can't confirm it.

<div><br>
</div>
<div>I am thoroughly confused and baffled and I
need help.</div>
<div><br>
</div>
<div>I need to replace the head gasket on my 66
BJ8. Moss shows three different gaskets ranging
from $49 to $229. Moss shows a $64 complete kit
for all gaskets including the head gasket. Moss
shows short head studs vs long head studs and
they show a "High Strength Head Stud Set"
ranging in price from $8.99 each to $229.99 for
the "Set".</div>
<div><br>
</div>
<div>I have read (on the Moss site) that ARP makes
the high strength stud. ARP has asked me for
the length of the stud, the diameter of the stud
and the thread size. I have also read that
Summit sells the studs and they are asking me
the same questions as ARP.</div>
<div><br>
</div>
<div>So, the questions are what is the info on the
stud sizes, high strength vs regular strength
(same for the nuts and washers), long or short
studs, who to buy from, who is the source for
the best head gasket (what thickness) and what
else do I need to know. The manual says 75 ft
lbs of final torque in three stages. Should I
be a bit more than that or stick with the
book?  </div>
<div><br>
</div>
<div>As you can see, I really need expert advice
before I screw things up. I do not race the car
so it is stock.</div>
<div><br>
