W2 Intake rocker arm [ OFF-SET ] info needed !!

To me it looks like the rockers in the picture above are Norris W2 but they appear to have too much offset. If you look at the intake rocker on the left side of the picture it does not appear to line up with the pushrod hole below it. I would venture to guess that those heads require T/A rockers with a .500” offset. Again, just my guess from looking at the picture. YMMV.
