| Q: |
Will Dart big block heads work factory components? |
| A: |
Yes, Dart Iron Eagle, Pro 1, and Big M big block heads will work with factory parts.
The exhaust port location on these heads has, however, been raised .300 over stock in order to improve performance. If you currently have tight header or exhaust manifold clearances you may need to modify them in order to fit. |
