NOS Ram IV valves value
 

I was rooting around in my attic today and found a complete set of NOS Ram IV intake and exhaust valves, plus a few extras of each. I searched the forum and found a few listings for NOS valves being sold with heads, but nobody selling just the valves.

Does anybody have an idea what these are worth? I would consider trading for a set of NOS SD455 valves, may sell outright.

Thanks,

Mike
