Default Holley Carb Ink Stamp decode

Has anyone been able to decipher the ink stamp codes on production line Holley carbs? Specifically, I am interested in 1970 List-4555 for the 1970 Z28. Below is a photo I pulled from a Nova site www.chevynova.org, showing the ink stamp on top of the front fuel bowl, but there are also ink stamps on the top of the rear fuel bowl, secondary vacuum canister and another 2-digit stamp on either the driver's side airhorn or top of front fuel bowl. I would like to correctly reproduce the stamp markings on my 70Z project, but would like to understand the logic/meaning of the codes.
