What does that mean? I had a ford tech look at them and he thought they might be 428 heads...... Is that possible? I still haven't figured out how to down load pictures or I would be glad to do it. Back to the heads how good are they and what would be the aluminum replacement? I tripled checked the heads again and they are cast iron and the id is (C6AE-F). Thanks for all your time.
