That's not your head gasket, that's your valve cover gasket. Much easier to replace and definitely a DIY project. I'd check to see if the valve cover is torqued down correctly. If so, just go buy you a new one from this link: http://www.ahmotor.com/product/ahmcat1vcg.html. Unbolt the valve cover, remove the rubber gasket, line the head (not valve cover) with Hondabond (which you can buy here: http://www.ahmotor.com/product/ahmcat1mt.html), put the new gasket on the head, mount the valve cover, and torque it back down!
