im pretty sure it will bolt to the engine, but thats about it. nothing else will line up. dont quote me on this. and if ur gettina turbo ur gonna have to loose the header anyway so its not its not worth the $$$ tryin to get it to work. on top of that a h22 header isnt designed for a SOHC. Im guessing a proper header would net a better gain most likely. companies like comptech, dc, etc spend hours of testing i imagine for some reason. i dont think its really worth it.
