Ok so i want to know way before my friend goes on buyin a head for his car, hes plannin to just go for a head swap on his 96 accord. Now i remember on a thread that a member was pissed cuz he was ripped of on ebay from buyin a vtec head and they send them a non vtec. So how can you tell the difference on f22b1 to f22b2, i know duh just by lookin the valve cover but i seen people that change that for they can say they own vtec. But i noticed more people sell heads without the valve cover so how can you tell by lookin at it? My friend told me that you can look underneath the the head where you see all the valves but all i see 16, i know vtec opens an extra valves at an rpm range?
