Ford is being allowed to submit two different heads. One mirror image and one symetrical. So the GM guys and Dodge teams can choose a head like they already have and hit the ground with their feet running. Saw the mirror heads and they look just like the Hemi99. Plugs even in the same location. Larry Morgan helped out with those. What tees me off is that when the Hemi99 came out Chrysler wanted to keep a canted head on the books too until the Hemi took off. NHRA said no way one head only. I guess Force and Ford have all the pull in NHRA racing now.
