There are none. You'll have to do it yourself or have a shop do it for you.
I do them on a fixture on a lathe, but you can certainly do them by hand as well.

The mains are done in the block bores. 
Seems like for the mains you could take a couple spare main caps & bolt them together with nuts & long bolts then mount it in a vise...

You can,but we like to do them in the block we are using since not all block caps and saddles are indicated(located) exactly the same.Why cut too much or not enough.Crank to crank and block to block vary,clearence what's needed for a particular block and a particular crank.We see some cranks that need clearence on only one or two journals .

WE put the bearings in an old rod and carefully champher them with a bearing knife or other sutable tool.Them we dress them with crocus cloth lightly.The mains are done in the block bores.
Here is what I did. I went one step further. Tighten up the rod and cut the rod off with a bandsaw. Locate the rod bore on a lathe and take the outer side down until it is circular. Takes about ten minutes on a lathe. Now you have a two part circular fixture that can now be clamped on the outer surface in a lathe and the chamfering can be done in minutes by any competant machinist. I guarantee if you have an old rod and a case of beer any machine shop will do this for you on a Friday afternoon.

 Great Idea,but many don't have access to a lathe or machine shop.We do many different journal sizes.

I'm sure that most of the stroker kits come with BB Chevy rod journal so why not buy the stock chamfer HD bearings for your crankshaft rod journal size  I use the Federal Mogul HD rod bearings.
We find that a lot of cheaper kits still need correction even with the radiused or narrow-N bearing.

If you have to do that with the NARROW bearing you should be having that crank put in a crank grinder and checked with an arnold gauge because it's really got issues .

Not really,regrinding the crank negates any saving that buying a low cost kit gained in the first place,cut the bearings and move on.There are lots of cranks with big radius's and radiused bearing that are running fine.

to bad you could not take a cone shape sanding bit like for cylinder bores and do the barings.it is cheeper to do with a file though.
That would be a NO-NO,cone sanders would tear at the surfaces and inbed material into the bearing.Remember some of these bearings can have up to 3 layers and coatings.
