I remember there being a Ford head like this back in the day. Ended up being just a flash in the pan. For $8K I can think of much easier ways to make 100 hp. Impressive for just a head swap yes. But not a very good dollar per hp gain. I question the reliability of a 4 valve pushrod head anyways. Maybe these are better then the other ones I've seen.

yeah I think that same company makes 4 valve heads for windsors also, a couple different versions if I remember right
