Since reconditioning top end, maybe cylinder head has cracked? Or problem with roller rocker arm on number two cylinder? Seems you have done everything it could possibly be.

Only other thing would be an electrical issue. #2 is the end of the firing line may be the power has sapped off.
Mopar fuel injectors can cause misfire codes even if they appear to operate normally. It is worth swapping no2 injector position to see if the fault moves to another cylinder.
Also sometimes failing crank sensors can cause spurious misfire codes, with no other problems apparent, I have seen this phenomena with aftermarket sensors that otherwise work perfectly.

That’s what I thought but when I read the post I got the impression there is an actual misfire occurring.
