I owned a machine shop when I was younger. For Pontiacs I always used Johnson 951R's and never had a problem. I used a lot of Melling RAIII and RAIV cams and never a break in issue. One time I was building a RAIII for my cousin and when I went to pick up the lifters they were loose in a padded envelope and rubber stamped "951R" on the outside. I was in a time crunch and had no choice but to use them. 30 yrs. later and they are still quiet, go figure...
