351-C Closed Chamber Heads

I have one set of heads from a 1971 Mercury Cougar XR-1. These are the 351-C Closed Chamber heads. (the ones with the MONSTER ports) They are in very good shape and are bare. I bought them for an oval track car I was building but never finished. They have been taking up space in the garage ever since. (I even have a fresh set of intake gaskets for them) Interested? $250 plus shipping and they're yours. Send me an email. ([email protected]) I can send you digital photos if you's like.
