from 85- or it is the Mercedes that look like
The Ford head

The first design had the low plug location (looking from the outside) but put the electrode in close proximity to the center of the combustion chamber---as seen in some of the pictures above. The design was based on theory-of-the-ideal and when actually put to the test the first engines actually made only a very little more HP than the production wedge versions. Very soon they moved the plug location, which made some of the other impediments mentioned above unnecessary. The result in the first tests of the revised version was an immediate jump of about 100 HP.

There was a character around Dearborn Engineering who was simply known as "The Thief". He conducted regular forays into the scrap areas connected with the engineering facilities. I got, from him, most of a set of the first-design parts. My whole intent was to use them for bragging rights as 'Garage Art'. They were of no value for anything else and I used them for trading material over a period of some years; finally having nothing left but a set of the low-position-plug cam covers hanging on the wall.

Are the low plug and high plug valve covers the same? It looks like you could swap them side to side from using the low to high plug design. Unless the bolt pattern is different, it looks like the driver low plug cover could go on the passenger upper plug side, and vice versa.

No, the first series has a different shape and is a little wider I believe. If you look at the second series head, there are bulges where there are valve springs.
