what letters were on your crank?are you using the same crank the bearings came from?if so put them with the same journals they came from and plastigage,the c seems to be the only diff letter on the crankcase at least.
Crankcase all B. Crankshaft all A. New case. Old case had one C. Used the journals in the same order as I removed them from the old case.

With the sizes listed, and more than about 5000 miles on the crank, step down 1 size from the charts for best results. The crankshafts are not hardened much after the K2 engines, so their journals settled in while matching their bearings. When I rebuild them, I usually find the crank journals to be about 1/2 size smaller than stamped (if the engine had good care and oil).
Just as an example: I am currently doing a near-sandcast K0 engine (these had the hardest of the cranks), and the numbers are the same as yours, except the alternator side hole (#5) is one step larger. The engine had round 12k miles on it. It is getting all Green shells, and one Brown for the alternator, as when I Plastigaged it with all new Yellow and one Green, it was slightly over 0.0020" on all.
Some of this seems to be due to Honda subbing the -422- series bearings for the -300- shells when you order them. These are from later-style engines (and cars), and the pseudo-Parkerized finish on the new bearing shells seems to be thicker than on the older -300- types. I just discovered this fact about 3 weeks ago when I got a partial shipment subbed (by Honda) to the -422- parts (I ordered the -300-), and when I Plastigaged adjacent journals of the same sizes, the -422- bearing came in slightly tighter. Thinking something went wrong, I wiped the Plastigage from both (all 5, actually) and repeated the test: the wiping caused the -422- bearings to all grow by a couple of tenths, leaving them slightly larger than the -300- the next time around. It's only tenths, but it is consistent enough to indicate there is a slight change between them.
Overall, try to keep the clearance between 0.0006" - 0.0020" for best results. Less than 0.0006" requires long break-in (but makes it really smooth!) and more than 0.0020" makes it sensitive to thinner oils on hot days.
Not to worry: even if you bought all BLACK shells, it would still run, just would take some time to break in!
