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/ahmcat1mt.html), put the new gasket on the head, mount the valve cover, and torque it back down!
