The actual Isky rockers have a distinctive look:

I have a set of those also that I am going to keep. Mine are not bushed. Did you.do that or RAS?

I think the other set must have been made by Crane for some other cam company to market. Who knows when the adjusters were.swapped. I found them when I was looking through stuff that I have had forever. Need to thin out the stash of old stuff that I will likely never use. I will have a pile of old parts in the 4sale section soon. Some used some never used but most are approximately 40+ years old.

In theory, there is no difference between theory and practice. In practice, there is.
