I believe it actually doesn't matter, copper does not harden on cooling as
steel does. Quenching may cause it to warp a bit, but I don't think this is
a problem.
However, I note that Mordy Dunst at Gasket Works USA no longer recommends
annealing copper head gaskets
>>>
ANNEALING: Recent testing has NOT shown a benefit to annealing (making
copper soft). Conventional lore and some metallurgical intuition has many
believing that annealing is critical. Using proper clamping force with high
quality fasteners and using GWG P/5 as directed has been successful in
NON-annealed copper gaskets. (April 2002). Motors that have a steel O ring
around the cylinder bore will however, benefit from annealing. In that the
gasket will seat into the O ring. But, it's reusability is doubtful.
