I have an 02 wrx and my timing belt slipped, I need to change out the heads, well I want to..but I have never done it before. Once the engine is out what are things that I need to do that I may not think of? The car has 130k on it. I am going to do all new gaskets, waterpump and oil pump I guess. Some people say to replace the head studs, is this true? My timing belt was just changed so that should be good. So basically if someone could tell me everything I should do while the engine is out that would be great. Or if you could link me to a thread that will have good information it would be greatly appreciated.
