Could use some help identifying some roller rockers

Awhile back I was able to pick up a pair of EQ CH318A heads that I believe to be the "good" ones.

I knew they were a set of the earlier ones from seeing them on the car, but bought them unseen other than that. So when they showed up with a set of roller rockers and ARP head bolts, I was pretty pleased. I did notice that one of the poly-locks was missing, but figured maybe it was in the the bucket of head bolts, and was glad that the rocker itself wasn't missing too. I didn't have any plans for them, so I just stuffed them in a corner and went on with things.

I don't have any plans for them now, but figured I should make sure I have a complete set of everything in case something comes up. And I got curious about the rockers.

Here is one of the rockers. Other than the 1.6 etched on the pushrod side, nothing else I can find.

Looks very close to the Hughes Stainless ones, but their note says:

Plus, the kit seems to include pushrod guides, but the studs look to be press in??

Yikes! Just noticed that valve has dropped, probably why the rocker was removed. Guess I will have to investigate that more.

Maybe this is a earlier Hughes kit or something? Anyone recognize them?
