The chrome on my 81 looked pretyy bad but a little elbow grease and some chrome cleaner got her looking good as new...well almost. Might give that a try before spending the money to have everything re-plated.
Be exceedingly careful changing these head gaskets, its easy to damage the oiling system and destroy the valvetrain. It looks simpler than it is. Dont re-start it till the timing belts are replaced, if they havent been already. The cams must be aligned perfectly or valves can hit pistons.
