Aluminum Hemi "Replacement" Heads +10HP
I see NHRA gave the Hemi racers a late Christmas bonus by adding HP if you run the aluminum heads. I know they give the aluminum heads more intake volume (198cc) vs. the iron heads (189cc), but less exhaust port volume. Do the aluminum heads actually make more HP?
I think Billy Nees was behind this. LOL! Just kidding Billy.
