I thought it might be, since the intake was. Wouldn't have made a whole lot of sense for him to get the intake for the 2.0 and the header for the 2.3...

That 2.0 is a great little motor. I ran one when I raced mini-stocks and would eat up the bigger 2.3s with it. Now if you could just lay hands on a Cosworth twin-cam head for it...
