Hmmmm. The wheels in my head are spinning again

That will work just fine. I stopped using press fit years ago. Once you peen it, that thing ain't going anywhere.

I also learned something years ago. After peening I always take a paper roll and just lightly buff the tube so the lifter never rubs on it. That way, it can never wear a hole in it.

I had a couple of lifter bores get holes in them. I think the edge of a junk set of lifters was rubbing on the tube and put holes in it.

After replacing the tube I started buffing the tube down so nothing can grab it.
