Alignment with ductile-iron rockers?

So, I'm guessing Isky rockers? There is a well known issue with the trunnion area being to wide.... If you narrow the hold downs the rocker will still rub the rocker stands... The fix is to mount them in a lathe and narrow the rocker... Your saying .080 which is probably about right but I always cut .090-.100 so you can use a steel shim so the rocker doesn't rub the aluminum hold down...
