Very interesting! We are now seeing comments that call for torqueing cold as well as hot.

However, I agree with JoeK that values used for torqueing when engine is cold would be different than values when hot.

I need to do a little checking; a member in our club had to torque the silicone gasket many times before things settled down, but I don't know if he was re-torqueing cold or hot.

I am also going to research some gasket manufacturing data. I'll let everyone know what I find.

Edit Note - I just read a FelPro paper that stated re-torqueing the head bolts with the engine hot. Does anyone have other manufacturer's data?
