The engine is bone stock with 75000 miles. The first time the valve covers were off was when I put the rockers on a couple weeks ago. The pushrods were brand new Ford Racing Hardened ones I put in with the rockers, same length as stock. Thought it might have been the lifters frozen all the way up, but I couldn't get them to go down by pushing down on the pushrod. It just seemed odd that both valves on 5 cylinders were one way and both valves on the other three were another. I'm planning on getting heads in the next few weeks anyway so I'm not too concerned, just curious. Thanks for the replys, maybe I'll never know for sure.
