I always use a dab of copper grease on the threads - works for me.

I think the worst thing you can do, particularly with alloy is to over tighten. I made a set of new unplated steel washers and go to 28lb/ft and have never had any gas/oil leaks from the head joint.

I always thought that to anneal copper you left the red hot metal to cool slowly at room temperature. Do put me right if this is incorrect.

From previous post on other lists I remember this subject coming up and the answer was that it matters not for Copper whether it is quenched or not - result is the same.

As stated ,it makes no difference with copper if you quench or not.But quenching hot does help make most of the dirty black oxide fall off . You can clean the rest up with a "scotch" scouring pad or pickle overnight in a citric acid solution.
