Lifter tube peening tool

My tube kit came from Direct Connection. It had a cylinder with a rounded end. I ended up not oiling like that so I sold the kit. Wish I could provide a pic of what I'm talking about. I just went with the oil pump porting and lifter valley crossover tube.
Yeah all those kits are apparently discontinued.I'm using solid lifters so don't need any oil to the lifters plus that's 16 leaks.My machinist has done this in the past but he insisted I do the work because he's busy.I also drill,tap and install a plug under the number one main feed to the left lifter oil galley.
