W2 Heads Rocker Arms

70aarcuda is correct. The rockers are the same. The shafts are offset drilled on the race heads which is why the stands are milled off. I think the long valve econo heads use a cast in stand that is repositioned to use a standard center drilled shaft but the rockers are all the same for any of the W2 heads.

The exhaust rockers are the same as standard head rockers the only difference is the left and right offset intake rockers.
