Not sure if it lets oil in or out. From dirt grooves suspects a lot comes in. Often see them just drilled but not sure if ever this way originally. Based on the observation of pattern on bearing and book attitude to grooves under load I ran mine with no holes but altho not a racer suspect a mistake. Austin presumably had a reason.
Some sort of shallow relief at the parting line as original seems desirable/necessary. Dont think this ran to edge.
