Thanks Mike - gave me the leads I needed. Interestingly in the end
the torque of 140 in-lbs is standard for 3/8" steel bolts in
Aluminium.

I'd check again. The bolts on my SD1 cylinder head are approx 3/8 and go
into aluminium threads. 70 ft.lb.

They're 7/16" which is not even remotely "approx 3/8".
