Gonna have to disagree with you there, I've gone through this every time I do a honda lower end.

You're matching the bearings to the crank, that's it.

In my experience, if the crank is damaged and needs to be polished or otherwise cut, replace it. Honda's hardening process on their cranks only gives a few thousandths of hardening, and then you get into the softer inner material. If you cut too much, you compromise the strength of the crank, and you'll have tuning and reliability issues down the road [been there, done that].

Also, you shouldn't consider line honing the mains on the block unless you really want headaches.

So, what you do is match up your main bearings based on how they clearance out, and go with slightly over or under sized accordingly PER main. You're not going to get the same size bearing at every location without a lot of work and luck. Rods are the same way, match the bearing needed with the journal it's going to ride on for proper clearance and don't worry about trying to get them all the same size.

For the record, this is the method I've used with OEM honda bearings, and, as with my car which I rebuilt the engine 7 years ago, aftermarket bearings.
