Large Port Commando Heads

I recently bought a pair of unfinished Large Port Commando heads for an engine I'm building, and didn't realize how small the chambers are on them. They are too small for the combo I have, so I'm putting them back out for sale.

These are unfinished heads, and they need guides, seats, and some machine work.

I am asking $750 / OBO + shipping. PM me if you have any questions. The heads are in Coeur d'Alene, ID.

Thank you.
