Yep, been there, done that.

I wound up with two possible solutions. I forget the exact dimensions, but 
there are Mr. Gasket 3" studs with a knurl that is almost exactly the same 
as the stock studs which I seem to recall as .560 or something like that. 
These are 1/2-20 studs. Nice and beefy.

If you want off-the shelf from the go-fast places, Moroso has 1/2-20 studs 
3" long that come in 5-packs. Those have a larger knurl (.615???) so you 
have to ream the holes out to get 'em to fit. I was doing a pile of hubs 
when I did this, so I contacted a tool supply place and got a proper sized 
reamer and then get the hubs and tool mo a machinist. I still have the 
reamer (somewhere) if you go that route.

If you need the Moroso part numbers, let me know. I have a few spares in 
the garage (in the blister pack), but I got 'em from Summit Racing.

Now the bad news - I'm pretty sure the only way you can get 3" studs in is 
to pop the hub apart. The long studs won't clear the bearing carrier.
