From an estate sale motor. There is moderate to heavy carbon buildup that seems come off easily, but it does need cleaning. Otherwise it looks sound with no obvious warping or cracks. As mentioned, the cylinder bore on one piston is cracked so engine block scrap, but all other parts are there.
This head looks good and is complete with bolts thermostat. I pilled the head and discovered a cracked water jacket.
