In some senses there is no difference between the GE and GW heads ; after all it just a name on the valve cover. However, in period heads badged as Weslakes were the race versions (Weslake mk1,2,3,and 4), only the last version having the inclined carbs. Gurney then developed a detuned, cheaper casting based on this mk4 design destined, he hoped, for a Ford high performance road car program; which never transpired. As a result he was left with a large number of these heads and those are the ones that would have been badged Gurney eagle. Since the valve covers can be swapped between the 4th and 5th versions, the name on the cover is not necessarily an indication of what is underneath!
