Closed chamber heads. Came off of a running engine. small scratch on the deck surface, happened during removal. Will come off with normal resurfacing. There is a broken tap in one of the exhaust smog ports, didnt leak. All the other ports have plugs in them. I'd really like to not ship them. I'm located in Central New York. 100 bucks for the pair. Will do a straight trade for a used, rebuildable sure grip unit for the 8.25 in my D150.
