SB Crane Retrofit Roller Lifter Issue

I saw this over on the Hughes site:

Before purchasing the HUG5008 retro-fit lifters, be sure to check the lifter bores in your block. The photo above shows an unmolested 360 small block. As pointed out by the arrows, some of the lifter bores are chamfered, or counter-bored. We do not know why Mother Mopar chose to do this. As you can see they are randomly bored to differing depths. The problem with this is that when you want to retrofit your block to a hydraulic roller cam the lifters that you need to use (HUG5008) may come up high enough that the oil groove around the outer perimeter of lifter becomes exposed into this chamfer. This is not acceptable. If your block has these chamfers, either find another block or give us a call.

The picture they have over there does not look like mine but the problem is the same: sloppy and inconsistent machining when the block was manufactured.
