Yes, they turned out to be marked just like your picture.

It appears the shafts that these were bolted down to were over torqued, as they wouldn't come off over the thru holes. I had to gut the shafts in 2 to get the rockers off. No biggie, I have plenty of shaft sets laying around. Unfortunately, quite a bit of galling going on from what appears to be some low oil pressure. I little work needed.
