(quoted from post at 22:25:45 01/13/17) The ether put it to sleep. Pull the injectors and get some oil on the rings.
(quoted from post at 08:34:18 01/14/17) The oil pump may be installed 180 degrees out of place too, which will through off the injection pump 1/2 turn also. Have seen it done on other JD engines that the injection pump is driven by the oil pump. One mechanic I know didn't feel like dropping the pan to correct his mistake and just pulled the injection pump drive shaft and turned it 1/2 so the internal dots no longer aligned..
(quoted from post at 12:48:14 01/14/17) Fifty percent chance either right or wrong. TDC is for both cylinders 1 and 4 as they rise/fall together. When 1 is on TDC after compression stroke 4 is after exhaust stroke, and vice versa because the CAM turns half crankshaft speed. When at TDC, watch the rocker arms, for 1 on compression both arms will be loose, and exhaust almost closed and intake starting to open on 4. Still could have the oil pump in 1/2 turn off IF the CAM was not in the right spot..

We weren't trying to run it on ether, just trying to start it. Used a small amount. The valves were fine when we reinstalled the head. The tractor was changed to a 12volt system by previous owner, starter also has 12volt solenoid.

Any use of any amount of ether causes pressure spikes above normal operating pressure .
