how much should a single cam vtec head cost? and what else do you need for the swap?

 

You can get a used one for around 100 through 200 bucks on ebay. You will also need the head gasket kit, new timing belt(bigger one with more teeth), and of course do the water pump also. I've never done it, but i've read about it. I think there is some vtec wiring you wire up also, which should come with the head. Not sure though. You can do a search for mini me and probably find what you need to know.
