Default Torq Specs

I just removed and reinstalled my exhaust elbows for an inspection of elbows and manifolds!
I know that the torq specs for the elbows is 20 ftlbs, but is that a cold spec or do I start engine and let it warm up and retorq them?
Its a 1995 mercruiser 5.7 a1g2!
As alway any and all help would be great!
Thanks !
Don

Thanks Mike!
The manual I have only states that the spec it 20 ft.lbs.
In the dark ages we used to retorq after running engine up to operating temp!
So I guess I wont retorq those bolts!
I have not done any engine work in many years!
Thanks for the input!
Don

I torque them a little above spec and never touch them again until I need to.
