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.
