Crankshaft stamping

[Blaze0010]

Finally got the chance of measuring the oil clearance for both main and rod bearings.
Rod bearings appears to be in specs (0.020 - 0.051 mm) with a good 0.038ish on all four.
Main crank bearings seems just a little above specs (0.015 - 0.033 mm) with measure going mainly I estimate between 0.0035 to 0.040.
I’m using ACL STD size bearings, not the racing one.
Not sure if it’s worth to have the machine shop grind them and purchase the undersize one, or if these are still good, considering i’ll mount the 20v oil pump that should have higher oil pressure, maybe with a slightly thicker oil.
Any suggestions is welcome!
