Shims and spacers are usually required, all are ok as long as the rocker has SIDE clearance.
Those are controlled by the snap ring.. they are wrong..
send them back for replacements.. they should line up
perfectly... you dont put spacers on those
EDIT
send Jesel a pic of them so they see the issue.. they will
replace them.... if need be they can move the snap ring
grooves over to center the rockers if they are in spec
now.. they may charge you for that.. but it would be cheap..
how is the push rod on those 2 sets.. does the push rod show
to be off... measure what it takes to center them so
you can tell Jesel
