The 351N heads were the best factory cast iron heads ford made. I dont think they count though, they never came on a production vehicle. They used to run them on circle track cars until they outlawed them, they also ran them in factory drag cars in the late 80s to early 90s. My old boss has a set but he wont come off them. They have 195cc intake runners and 78cc exhaust runners with 2.02" intake and 1.60" exhaust valves. They pretty cheap too, a couple years ago they were $375 bare.
