With regards to the question of re-torquing a head after a heat cycle, I have a BMW 328 engine with a Bristol head.
The specialist who built the engine recommended that it be re-torqued as soon as the engine had had a few gentle running-in miles on it. It has, what looks like, a solid copper gasket and it did, indeed need a bit of 'nipping down' after said period.
I seem to remember that the figure he quoted was 35ft/lbs.
