Lifter Valley Crankcase Vents

I am considering installing short stand pipes in the lifter valley crankcase vent holes in an effort to help control Windsor and oil wrapping itself around the rotating assembly. I have completed the Paul Kane oil system/ drain modifications so I wanted to test for any downside for installing the vents.

Windage.... I hate auto spell correct....

If you have a roller cam , I don't see a downside. If you have a flat tappet , I wouldn't do it. I honestly doubt you will "see" any gain from the mod. Others may have different experience.
