How often do you need need to re-torque header bolts on a 340?, is 20Ft Lbs the torque spec for these bolts?

I would use lock tight mine came loose all the time with my black jack headers, but since Ive put tti on everytime I check them so far they have been tight, As far as torque I just make them tight.

I have the cheap Hooker headers but good bolts and copper gaskets, and haven't had to re-tighten any bolts in three years.
