This is usually not adjusted for, it's one of those things with stud mounted rockers. However, you had a thought about adjusting the push rod guide plates and this is a bit on the right track. Isky sells a two piece guide plate, you can use this to offset each push rod to shove its rocker over a little. This will fix the condition if your existing guide plates are the cause of the offset. If the cause is the result of machining discrepancies where the stud and the guide aren't in the same line as the push rod, you can lean the rod a little, very little, to shove the rocker over. You have to watch for binding the push rod in the guide when doing this, which is the limit of your adjustment. Keep in ming that heavy springs will tend to bow or bend a leaning push rod so it this is a full up race engine expect failures of the push rod every so often. Doing this on a ball mounted pushrod can result in the rocker tipping at the valve stem which will wear funny if it doesn't break the rocker out right.
