Well my much troubled 451 ended its career two weeks ago. Got on the freeway, and she began misfiring. Looked in the mirror and I couldn't see behind me the coolant was going out the exhaust so bad. Wrecker ride to the garage where I get it worked on. After sitting a day, the oil became overfull. Pulled the heads and found what you see in the pics:
