Dave, that sounds logic. Thanks again.
What an interesting arrangement. The spark plugs seem to be mounted above the inlet. Do you know why inlet and outlet valves changed the position in the first and fourth cylinder?  Attach file:  (30.98 KB)

Gerd, may I take a swing at this ball? I believe the valve arrangement is to have no two exhaust valves next to each other. Possibly, the thinking was that having two exhaust valves closely situated would result to too much heat in a small area. Two intake valves next to each other would not cause excessive heating of the area. Engine metallurgy at that time was developing to cope with increasing power demands and hence more heat generation. Let's see what the experts say about this.
(o{I}o) Edit: Cylinders 3 and 4 do have adjacent exhaust valves, but they are in different block castings. Edit, edit: Plus the same casting could be used for both cylinder blocks.

Let's see what the experts say about this. John, thank you for taking the swing at this ball. The engine has [OI IO IO][OI IO IO] from the first to the last cylinder. I'm with the idea, that this valve arrangement has at least thermal aspects. If the engine designer tried to string out the outlet valves this would have been a creative possibility. On the other hand the heads have an imbalanced heat distribution. Well, no head gasket necessary, that tempers the wind to the shorn lamb, so to speak, since the head gasket would be the weakest link. Thanks again John! Attach file: (24.57 KB)

Thanks for the link also! It was a lovely day for the show in Galena downtown. I wonder if I or my wife are in it? The organizers did a wonderful job as did the owners who graciously displayed their Packards. Well worth my 2 days of driving to get to it !

Quite a regular

I had a marvelous time, and tip my hat to Packards of Chicagoland for a terrific week. It was like an oasis in an island of heat - 100 F in Kansas City, 80 in Galena, then back to 100 in KC. I should have just stayed there!
I'm posting my favorite pics (the 1920 Twin Six on the road), but I have more if anyone wants to see them. No sense repeating what others have posted! Attach file: (63.05 KB) (67.95 KB)
