If you own a Neon chances are you will have to replace the headgasket 30 or 40 times before you shitcan it. You can do this job yourself but it does require some mechanical aptitude and maybe a mechanic willing to give you advice. If you do it right it will last the life of the car. If you skimp you will blow it soon after guaranteed! Anyway, here is a link to my site and how I changed my head gasket myself http://www.chucksirois.com/projects/projects.htm

OR you can just go to chucksirois.com and click projects on the left

Hope this helps
