they aren't stock rockerarms. this is a pair of Zeeker heads with Zeeker/Dove rockers and the geometry is terrible. the customer used shims to try to correct it.
the rockers are too short and sit almost on the inner edge of the valve, they also didn't clear the 1.625 springs, even though they were already clearanced on the underside.
i'll correct the geometry for him without the use of conventional shims under the shafts and make a new stand to replace the damaged one.
i'm not sure if anyone cares, but maybe i'll post pictures of the completed repairs.
