When bolting down a cylinder head I tend to use a torque setting to ensure all round uniformity. Is there a recommended torque setting for the nuts that sit on top of the rocker box for a DB34 Goldstar?

I'm unaware of any recommendations BSA gave for the Gold Star, but torque settings in later BSA and Triumph manuals for similar covers with gaskets (e.g. Trident rocker box) are 10 ft.lbs. for 5/16". This is significantly lower than the 18-25 ft.lbs. those manuals recommend for 5/16" fasteners when used for serious clamping operations on pieces with thick cross sections, like heads or cylinders.

Thanks - that makes perfect sense as I am not torquing down a cylinder head so I will go with the torque setting for the rocker box cover.

And speaking of GS rocker box studs. I and many others have replaced the studs with socket head bolts that works nicely. I believe it's a good idea to lube the threads with 'anti seize. This allows fitting the rocker box on the head after the head is bolted on. In a matter of minutes you can do a 'look see' at the valves/springs. An added feature is making it simple aligning and fitting the push rods during engine assembly.
But of course all of you are now using the composition rocker box gaskets vs those OEM paper POS gaskets.
