Looking for a cylinder head for my rigid b31.
have a B31 head. But, if I do it's at the back of a shelf behind a few hundred pounds of other BSA parts (there are heads back there, but they might all be B33 heads). If I do have one it will be rusty (no big deal) and certainly will need new valves and guides. However, before even considering shifting a few hundred pounds of parts, how much is such a head worth? Please don't ask me how much I want for it, tell me what it's worth.
