Picked up a set of stock 426 hemi rocker stands some time ago at a swap meet. Started to put together the valve train assembly and one stand has the shaft holes too close together. After measuring things out, both holes have been drilled .031 too close to the centerline of the stand. These are stock factory stands. Indications show they have been mounted at some time on a motor. It is one of the 2, 4 oiling stands. This was going to be a spare set of valve train assemblies. Anybody ever see this before?
