While were looking at this side of the motor the oil pan will block off the oil return if you have an oil pan gasket lay it up there and you will see the oil return for the time tunnel is blocked off.

Yes the oil pan will cover most of the original hole that was there that's why there is more of a slot there now. I have also drilled and tapped 4 1/2NPT holes right under the cam next to the back of the mains for oil drain back. I know if gets into the swinging assembly it will cost HP but for now getting the oil back to the pan is more important than windage loss.

Are you bushing the lifters ?????will the lifter uncover the oil hole when its all the way at the bottom or all the way at the top.THIS is another big problem.... if so bushing the block is the easy fix... I would pressurize the water aND oil before I did anything..

You don't have to bush the lifters but I'm thinking you'll need a taller than normal lifter so that when it's at the bottom the hole is not uncovered I've had both style blocks the one with the oil hole behind the lifter and the one with oil hole in the center of the lifter. If you measure from the base of the cam to the top of the oil hole that will tell you how tall of a lifter you will need

The ones I have seen all take the low deck cover however the block could use a tall deck cover if new holes are made.

check every lifter to be sure that you are ok .they look low when they drill the galley from one side only the hole some times will wander of course. That is why other blocks are drilled from both directions and intersect one another

I just had to drill and tap (2) new holes on my R3 block for a stock 360 timing cover to work. Not a big issue

Are those coolant passages in the deck correct? Something funny looking there.
