umm....the subject is my question
Yes I am a total n00b and was wondering about the "head" Where is it, what does it do, how does it do it? If one was to obtain one, is it possible to DIY in ur home garage or must it be taken to a shop? Any suggestions as for a good type of head to get?
these q's are for a 98+ integra GSR

Also what are the costs involved? thx
