I'm referring to the "big F" head. |

The "Big F" head was not available on 427MR productuon engines. It was offered to Ford sponsored NASCAR race teams and then was apparently available over the counter and made NHRA legal.
If I recall, the ports are a bit different, and the "F" is located next to the #1/#8 spark plug, not between the center plugs as found on the pruduction "F" heads.
There were a variety of MR head castings with SK numbers. SOme worked better than others, but the "Big F" ones were apparently based on one of the better SK variations.
