Hydraulic cam core Used for a.roller regrind?

When the new cam dynamics roller I intended to use in my small block chevy wouldn't fit (rods hit the cam lobe), I bought a small base circle regrind roller from Americam, ran very well, was about half of a new custom roller. Ita cast core, not a billet, and I used new lifters.
I have no idea if Americam is still in business. (Southern California).
A roller regrind kinda automatically makes it a small base circle cam.
Edit: I got the name wrong, it's American Custom cam. They saved my maxwedge billet roller, and supplied my small base circle small Chevy roller. I'm probably gonna get a roller from Joe for my new Opel engine.
