Copper only needs heating to dull red to anneal. Heating to cherry red could end in tears (if you are using a gas torch). Then either quench or allow to cool. It makes no difference to the resulting softness/hardness. Scrub With a scouring pad or scotchbrite and water to remove any scale that forms during heating.
With a solid gasket your joint faces must be in very good, flat condition. With an engineer’s straight edge or ground parallel test bar you can check for distortion with a feeler gauge. I would think any distortion, or hollow areas over .003″ on either the head or block would require rectification.
