I would start with the .492 reamer and then measure the hole afterward and see what it actually cut. Either reamer should work, but it's easier to take material off than put it back on. We usually shoot for .007 to .010 interference with steel hubs/axles and ARP studs, which have a fairly coarse knurl. For a finer knurl, I'd go towards the lower end of that range.

Tobin,
Thank you very much for sharing that info.
I’ll try .492 in a piece of scrap and press in a stud to see how it will work out.
