That would have been ok, except the output nipple will not screw into the 90 degree housing, it will only screw in about 1/4 of a turn before it gets tight. Either the female thread is out of specification or the nipple is. The supplied nipple will screw into the FL-820-S filter ok.
Ideally I thought the output should be the same as the valve cover adapter is. Then you could use the Motorcraft FL-1A or FL-400-S or equivalent filters. I use FL-820-S filters on two of my other vehicles so I thought that would be OK.

I would bet that the output side is also 3/4-16 to use a FL-1A type filter and you got the wrong nipple

The threaded nipple fits an FL-820-S filter, It is too large to fit the FL-1A filter
(I tried both filters) The nipple will not fit the 90 degree adapter it came with. I tried both ends. The filter pictured is a Purolator equivalent to the FL-820-S.
Besides I think the adapter would hold the filter too close to the block and interfere with the oil drain back tube.

Randall. (https://youtu.be/9YXjaxxC7rE?si=3hjP2ezEiBit84gL) that is a good test video.

i am surprised that the gallery baffle at #1 cyl. was modified by ford in 1928. it was raised by about 5/16" to the height of the lifter boss, aswell the timing housing opening baffle was lowered.
it doesn't seam like a lot of oil going into the rear sections of the gallery.
i suppose that on the first blocks too much oil was directed rearward because the pump delivers lots of oil.
i don't know but maybe not enough lube to the camgears?
