Solid lifter information wanted

The lifter bores on the block are in excellent shape. The problem is oil bypassing the oil band of the lifters with a solid roller cam. I have the Direct Connection racing manual with all of the diagrams & instructions. I'm going to take the block, the tubing, the peening tool & the manual to a machinist that is highly recommended in the Mopar community in Texas to have the passenger side sleeved.
