I've got a pair of 452 heads from a '78 440. The intake surface of one of them is totally flush, while the other has a raised surface where it touches the intake manifold, like normal. I've never seen a head smooth like this on the intake surface. I'm sure they came off the same engine. Did Chrysler ever do this?
