milling the main for oil passages?

[Drift_FX]

i was looking to run theses bearings, but i have a few concerns...
Calico coated 5-Hole Main Bearing Set - Engine - Mazworx

since mine is on a det block i will have to machine out the oil passage for the other 4 holes. does anyone know the measurments for this? and wouldnt putting an oil passage under the bearing cause it to be more likely to spin due to pressure behind the bearing? or does the extra oil between the crank and bearing negate this?

i have a pretty built/high reving sr22vet (det block) and milling the main is pretty foreign territory. but im trying to make sure my bottom end can keep up with my head...

has anyone done this? and what are your opinions about this bearing setup for det blocks? also is the calico coating worth the extra $80 or is kinda a gimmick? im not to familiar with this type of coating...
