Thanks for the info. Is that kind of typical? They would have had to build hundreds even thousands of those in January of 1970 or did they just all receive the January date code regardless when they were built after January?

It's typical.When supply ran down,they released them all in single lots as needed,but only narrowed it down to the week assembled.
As Dave said,that;s the latest I've seen so far too.
014= 1970,January,4th week.

I have a 70 05B L78 Nova, has a 013 4557 on it. I would say that 0023 is some kind of over the counter piece.? Why is it stamped with 4 digits.?

That one would be considered a service replacement for your car.
Holleys assembled after 1972 used a 4 digit date code.
0023=
002=2nd day January
3=1973.
