That thing should fly! The Stage VI's are a good head. My 496 also had the stage VI's on it. With the tunnel ram and the stage VI's you will need the intake spacers. Mopar does not make a tunnel ram just for the 440 and the Stage VI's. I ran the intake spacers on my 496, The one thing I did not like is the dog leg in the port with the spacers. just do a good port match and you should be fine. When you get that thing running I would like to see it run. ??? why would you need a spacer?? did they change the shape and dims of the head compaired to stock?
