This head has 1 trashed dome, and the center dome has a very minor little bit of deto out by the edge. It is marked limited and the domes measure around 34cc. I understand this to use the same domes as Blowsion or Pro-tec so getting another dome should be easy. I don't have o'rings, or upper bolts but I do have the lower studs and nuts. Asking $175 shipped OBO.
