Can anyone give me an idea of what an NOS 67 L-88/L-89 head would be worth. It is dated 4.20.67. I recently picked one up and plan to sell it but want to be fair with pricing but also not get taken.
I have dealt with the 842 closed chamber heads and 074 open chamber heads quite a bit but do not know much about the 392 heads.
Thanks,
Jason
