If you diy it, just taking off the manifold is not tough. The worst part is getting under the car to take the bracket off the bottom. Other than that, easy. And a new manifold gasket is about 15 bucks. The only thing to worry about is getting all the old gasket crap off, or else your engine will rev like a bich. But take your time, make sure all the metal shavings are out, and you should be fine doing it at home.
