ex has the single cam vtec head. I'd imagine there is a swap like on b & k series, but I'm not familiar with it.I have the entire motor (it needs an oil pump), minus the intake manifold out, so no injectors, fuel rail, or throttle body. the vtec solenoids , I'm sure are still there, and the valve cover has not been pulled since the last timing belt replacement about 30k ago, so the head is complete. I'm not trying to force something on ya, just laying out another option.
