SB rocker arms and shafts

Hey everyone I am looking for a good CLEAN used set of small block rocker arms and shafts. The ones I have a covered in a baked on impossible to remove black carbon and my shafts have deep scratches running the length of the shafts. I just want the stamped steel sets but I need full sets. If anyone has a set laying around let me know. I don't want to break the bank on these if possible. thanks
