My SBC has the 2 piece rubber rear main seal.
Pull the cap, slide one piece around to the top, place the bottom and install the cap.
I hated the wick seals.

You're drilling into the middle of 2 separate bores with different diameters.
Not an easy task with a hand drill.
Maybe if you also dropped a bushing into the bore on the right with a precision pilot slot chunked out of the side of it?
Sliding a thickness blade gap gage on the opposite side of the lifter bore will jam the old lifter in the bore and will send the drill straight where it belong. Using the original pin you can see if the drill will be in line with the lifter flat face.

I should have done that before drilling to check the clearance between the pin and the lifter since there is no spec for it.
The original pin could not have been straight since the lifter had some circular play.
But maybe I could have gotten an average distance.

I just checked the clearance on the screw pins.
This is not the best way to do this but I don't have a narrow bladed gauge set.
I could cut them down but this is what I got.
The gauge has wide blades so I raised the lifter without the pin installed, lowered the lifter keeping the gauge in place and inserted the pin.

I started with the smallest feeler gauge I had (.0015") and the pin went home.
I used a .002" blade and the pin would not go in.







All of the other bores would take a .0025" blade with the pin going home.
So, on the lifter bore I was concerned about the most, I choked on it and drilled app .001" toward the lifter bore instead of the smaller hole to the right.
Keep in mind the new hole moved left app. the width of a human hair.

sounds about right.
i think mr. jean was wanting the feeler on the opposite side of the pin hole with the flat facing the pin hole. this would move the lifter body as close as possible to the pin hole side and offer maximum resistance to mill walk. when the feeler is pulled standard clearance or near about would be maintained.
if the mill is turned say at 600 rpm as most drills can do and slow steady pressure, the mill would not really want to walk. mills are pretty tough, i slit cut harden drill pipe with 1/8 mills and if you did not crowd it, cut easily without distorting the mill.

That looks like a lot of cuts and a pita.
But it worked.

Rejean reminded me of checking the clearance.
It was on my mind since Toejam mentioned it earlier.

But yes, that would prevent a full on walk toward the lifter with the feeler gauge shimmed on the opposite side of the lifter.
That would push the lifter up against the right wall of the bore.
However, the pin does enter the lifter bore slightly so the flat would have to be facing the bit.
This leaves clearance between the flat and the bit.
And that can still allow you to drill up to the face of the flat, creating resistance when the good lifters are installed.
