These mildly ported square port heads are from a running engine and are in great condition. Would make a great Christmas gift .Probably could bolt them on and run them , but should be gone through just to be sure . Removed from a 468 drag engine because we got some aluminum ones . Auction is for local pick up, but can quote shipping on request. If you have any questions call text on email them to me . (216)-214-4569.
