Touch up valve job and a light skim of the decks.

New springs, rocker arms, stem seals. Wrapped in plastic wrap sitting in the corner looking for a new home.

800 takes 'em away, local pickup only. located in southern, NH 40 minutes from Boston.

FYI: 6X heads first came out in 1976. Great heads when applied properly. By that I mean making sure you're meeting the octane requirement of the engine. Too many guys think they're going to trick Mother Nature by running too high of compression.
