Richard, you are correct, they are not cut.
However, my plan if they are a usable height such that the dogbones sit low enough to encase the top portion of the lifter, is to modify the dogbones to sit flat by grinding a small bevel on the bottom rear edges. The existing block surfaces are already mostly flat and perpendicular to the lifter bores, except for a little radius on the back edge. Instead of machining out that radius as the factory did, I was planning to modify the dogbones a little. The slots in the dogbones already have plenty of extra room in them to not bind on the lifters even if they sat at a little angle, so I figured with a little bit of work, they should be just fine.

As usual, I am the novice here, so if I'm missing anything, please advise me. If I have to, I can have the surfaces machined, the same as the factory, but I'm hoping to spare that added expense if I can.
