And then there is THIS. These are later heads, but with cast in pedestals "econo" and clearly these rockers ain't gonna work. I'm supposing this rocker is for the offset stands and shafts, didn't realize the rockers were different length. Looks like a trip to my Bridgeport mill is in my future, as well as a hunt for the offset drilled rocker shafts.View attachment 1715535499

I think FABO member @Rocket has some very nice offset shafts for sale.

You may want to contact Mike at B3 and see how much actual correction you need. You may be able to just offset grind the shafts you have and use his kit to correct the geometry.

That’s probably cheaper than shafts, blocks and milling the stands off.
