4 cylinders for C-85 stroker

The cylinders of my C-85 stroker are worn out. I believe they may be original with as much as 3000 hours on them. Compressions 68, 61, 60 and 56. I'd like to replace them, but I  don't know whether to ask for C-85 or O-200 cylinders. I believe I want C-85 cylinders. Anyone know where I can get 4 of these babies?
