What would this set of heads be worth?

[y5mgisi]

A buddy of mine has these and he just wanted to know. IM NOT SELLING THESE.
Anywho they are a remaned set of heads off a 55chevy 265 v8. They seem to have real small ports but by running the numbers thats what they came up as. Does anyone know if these are perhaps "rare" heads that could be worth somthing?
Also he has a set of 70 chevy 350 heads that are 75 cc chamber that are also totaly remaned any idea on what those could be worth? Thanks!

Not really "Rare" but htey are getting harder to fid you might try listing them on a tri-five site I would say 50-100 bucks if there decent
