Note where the pump housing ports also go to the heads. This was usually the setup on 413's and not 440's but I have heard of the early 440 RV engines having it too although I've never seen one. All the ones I've seen have been 413's. These heads can be used with regular WP housings too if you use the block off plates. These heads have the WPH ports on the back but have the block off plates back there.
