No first hand knowledge of that company, but a good core can be sent to Schneider cams in San Diego for a wide variety of profiles. I've even discussed the possibility of putting a roller lobe on a stovebolt cam. They say they would need a steel, not a cast core to do that. 216s and early 235s had steel cams, but a sleeve would need to be fitted to the bearing journals to enlarge them to fit a 235 engine.
