I have a set of 1.5 Crane Gold roller rockers, shafts, hold downs and push rods. I pulled them out of a 340 engine. The cam was a Lunati with about 520 lift. Probably too much lift for these rockers? The push rods were "ticking" the rockers. (see photos) Looks like not enough to bend them. The shafts have some heat scoring. I think the rockers will need new adjusting screws and nuts. Are they worth selling? Your opinions please. Thanks.
