Your first post , you said you 1417-16 which is a set of self align for a V8 which would be OK.

Now you say you have 1416-12 which are NON self align . If you have non self align rockers , no wonder they wander off the valve tip!
BTW 1416-12 is only 12 rockers so one can only guess you mean 1416-16 ??

Yes,1416-16, If non self align rockers,what to do?
