Default Rod Bearing lubrication issue

Ok, I was just playing around with a stock set of rod and piston. I notice the stock rods have a hole drilled thru the rod all the way thru bearing and all. Also notice my ACl race bearings have a hole drilled in them. So why the hell does my H beam rod not have ANY holes at all? Should I get the machine shop thats putting this together to drill a hole? and if so, just 1 hole per rod and its gotta be matched thru the hole on bearing also im guessing. Just making sure my guess is right, can anyone back me up? There is one spot that has a hole drilled, and thats where the wrist pin goes, thats it. here is a pic of the rod....

naw, what imasking, is do other brands, like Eagle, and all the others, do they all have an oil hole going right to the rod bearing like stock rods, I mean it has to, why would stock have an oil hole, and not aftermarket...just trying to make sure. thanks for the input.

There is not a hole on the rod on purpose. You can also get some fairly high end bearings that don't have the groove down the middle. It's just the way they are. The rod if fine as well as the bearings.
If you think about it, if the rod had a hole in it to match up to the bearing's hole, the oil would just blow out the hole and wouldn't lubricate between the bearing and crank since there would be no pressure.

The hole in the stock rods is to spray oil on the piston and cylinder wall for cooling and lubrication.This also reduces pressure at the rod bearing slightly and causes a lot of oil to be spraying around in the cases.Typically aftermarket rods eliminate these holes for almost every make and model.
