Honestly those don't look bad and that you did not have any untoward operating issues is confirmation you could just deal with the head gasket. If you wonder (as do I) what caused it and suspect a ring issue (ditto) you might pull that piston and see if there's a bunch of carbon in the ring or something similar. If you do, be sure you mark the rings and place them EXACTLY as you found them in orientation and which surface is up. At that point you could also consider the honing suggestion if the cylinder measures within spec to hone.
Personally, I'd just do the head stuff and run it unless you're planning to race it or you tend to push the car hard. If it's a fair weather hobby car - run it. If you're a teenager and redline it often, fix it so it can handle frequent operation near the mechanical limits of its design.
