All I can say about the subject is that I came across it when I opened a NOS
head gasket package and a little slip of paper fell out with that
recommendation. So I would expect that there must have been issues.
Since then, I have been doing that religiously every time I have taken the
head off any Spitfire engine. I was at first surprised at the amount of
turning I had to do to get the proper torque after the engine warmed up.
It makes me wonder how any engine that was not done in that fashion could
avoid having problems with leaking head gaskets.
Cheers,
Joe

Joe,
Many thanks on that tidbit!
A couple of months ago, I had a pleasant phone conversation with the Moss
Motors USA rep and that was what he recommended (re-torque when hot).
Does this make you think that the factory had problems regarding the head
gasket? I seem to remember someone saying that the head gasket was a
problem area for the 1500.
I'm somewhat reluctant to go back and re-torque because a couple of months
ago I was attempting to replace the head gasket in a friend of a friend's
1500 MG and I managed to strip out some of the studs from the block(!).
What is the consensus of opinion on re-torquing with regards to this 1500
Triumph engine?
Is it a necessity or is it just re-checking? If necessity, hot or cold?
By the way, I torqued down on bone-dry nuts and studs, ie no lubrication at
all.
Cheers!

Not generally known, but the Triumph factory recommended that for Spitfires
at least, the head be retorqued immediately after running it up to operating
temperature while the engine is still hot.
