PLUG THOSE HOLES
When I only have only one torque plate I’ll plug the holes on the other side of the block with foam earplugs. They do a great job of keeping honing oil out of these holes. This way, when I change my plate to the other side, the oil or thread lube isn’t mixing with honing oil in these bolt holes.
