As I think posted earlier by someone, if the rockers are not fully rollerized and you just have those roller tip rockers then the rocker stud slot in some of them might not be the same length in some of them which could make for your issue.
I would check this out very carefully, and in fact if I had stock 1.5 rockers sitting around I would be really tempted when you get the new pushrods to start off with those on the motor to see what happens.
