When did Chevy change the oil groove on the rocker arms from inline with the oil hole to offset. On my '56 235 the casting numbers went from 5,6,7,8 and the oil groove is lined up with the oil hole. I also have a set that have 85, 86 etc. casting numbers with the offset oil groove. What year did the change happen? Thanks!
