However, there are differences in valve timing within these years. When these parts are used in a, say, 1941 216, will the valve timing match that of the later 216's?
I ask since my rebuilt 1941 216 fails the valve timing test shown in the 1942 shop manual.

If Chev made any change in a part they gave it a new part number so 1938-53 should be the same cam.
The steel gear shows 1937-39 taking one, and then 1940-62.
The filer gear fits 1937-62.
So to answer your question, if you put 1940 and later gears in a 1938-39 then the cam timing should be the same as 1940-62.
Your 1941 should take the same gears they are selling today and is unlikely to have 1937-39 crank gear.
