The open passage from the left hole (in pic) directs additional oil to the timing chain.

I would think with the front of the horizontle galleries being plugged with mini freeze plugs that the change is only a different MFR process cuz there ain't no oil coming out of there that could dribble down but I will defer to John on this.

John Kunkel I believe is correct, there should be zero pressure at that opening, the oil is just partially draining the lifter valley.

I would always use the mini cup plugs in the (2) horizontle galleries & I drill a 3/8 hole in the pass retainer plate & drill/tap the front of that sides' horizontle gallery for a blue aluminum pipe plug with a .015" hole in it on that side instead of the mini cup plug for a constant mini squirt past the plate onto the chain. But people have said that there is enough slosh in that area that the chain ain't hurtin for oil.

Stock plates used a bolt with a small hole in it to oil the chain through the lifter valley Some small blocks just had the bolt with the hole in it for oiling. Others just had the drip tab. I put both on my last build.

Yes & it is an 1/8" hole that you can easily drill in a regular bolt (& use the drip tray if you have one). EDIT & this is the top pass bolt, the other top one is a blind hole, the two bottom ones go into the valley (if there would be enough splash back there to warrant drilling the bottom ones (couldn't hurt/easy to do).
