Well, 351C was running a bit poorly, so I thought I would adjust valves this evening. After I removed valve covers, I noticed 3 pushrod guide plates were broken. After further inspection, I saw these 3 pushrods were bottoming out in the guide plate slots at full lift. Obviously I didn't check everything well enough when I built this engine. Should have been more careful with these 3/8" dia. pushrods. Luckily, no pushrods were bent, so I bought another set of guide plates at local machine shop (Which speaks Ford very well). I relieved new guide plates with end grinder and burr, installed them and set valve clearance. Now runs much better and even hits much harder. Just wondered if anyone ever ran into this problem before. Later, David Shelton.
