Oil gallery restrictor

[Hurst390]

I usually drill 2-5 mains to oil from both lifter galleys. Then I run a .040 restricted pushrod..
I wouldn't restrict a galley full of edm drilled lifters
I have restricted the drivers side galley in years past with a crane solid roller. Those lifters restrict the oil anyway and ended up with hardly no oil on the top left side and actually burned up a set of lash caps.

And when you drill to oil from the drivers side galley I clock 2-5 cam bearings to feed from the drivers side....

Thanks for the replies. As I mentioned earlier I was mostly curious what size hole would adequately feed one gallery of lifters plus valvetrain after reading .200 and .090 for hydraulics and solids.

I will not be installing a drilled pipe plug as a restriction. I am using .040 restricted pushrods.
