Mopar ( Tube Kit ) info requested !

I`ve never seen this done , or done it. Wondering why a guy couldn`t stabilize the tube and drill it ''before'' the peening process . ???? The hole would still be there, but in a diff. location on the sleeve
I was told the tube tends to want to rotate during the peening step.
Did you drill holes in the copper tubing to get oil to the lifters?
Yes.
