So Dama Elgin was one of the lead cam grinders in the day, and used to do some very good stuff (for back then). I believe he was the pioneer of the 5th cycle, which was acknowledging the use of overlap for cylinder fill. No rookie
However, their business model either changed or was acquired by someone else because they became "rebuild kit" parts for the most part.
In the 90s to now, their cams are very much the 204/214 slow ramp universal grinds, and my last set of Elgin lifters (1994-ish) looked like the base didn't fit well, enough that I put the new parts on the shelf and never used them
I wouldn't use if I could help it, but likely decent enough
