if you dont have any mechanical skills i suggest you save money now and take it to a repair shop.but if you think you can do it invest in a work shop manual its not very hard to do if you follow the instructions in it. if you have been using the car then after you have removed the head it will need to be checked by an engine rebuild specailist incase it needs skimming because of over heating the head warps.
