Schneider Racing also has cam but I think they are made to order.
You probably won't find a roller (if you're talking about solid/mechanical) that's "just a little better than stock." Most profiles for those are huge. Then, if you're wanting a smaller profile done, most cores are already ground for small base circles for the bigger lobe lifts/bigger profiles.
From what I've been gathering in my research, a smaller profile will have to ground from a full round core. Very expensive.
