Default f22b1 main bearings

muy f22b1 vtec engine has 22222 stamp on crank and ccbcc stamped on block which comes out to y/g,y/g,y,y/g,y/g. (that's yellow and green.)
with yellows in the block and greens as well..(I know it meant one half yellow one half green, but I wanted to see the difference in the bearings...)the yellow had a clearance of .0020, which is the service limit for journals 1,2,3 & 4...
here are muy books' readings
-oil clearances-
# 1 &4 standard .0005-.0015 service-.002
# 2 standard .0008-.0018 service-.002
# 3 standard .0010-.0019 service-.0022
# 5 standard .0004-.0013 service-.0016
I also tested browns and acl bearings.
these are the clearances I got with a dial bore gauge.....
green bearings- .0019
yellow bearings- .0020
brown bearings- .0015
acl bearings- .0025

any ideas
