droped kdp last week, got new [expensive] cover from freightliner. marked all gears and put back exactly as they were. replaced rocker arms and pushrods all in there original position. started to rotate motor when it started to bind, i put a little more force on it thinking i was on a compression stroke. took pushrods back out and had 2 bent on #2 cyl. one had a slight curve the other had more of a rather bad s curve. i worked with them and got them almost perfectly stright. part of what i need to know is it possible to still use them and what could have caused it to happen. could i have damaged the tappetts, i am sure all timeing is correct as i was very careful to mark all gears and never moved the motor after i removed the cam thsnks jimmy
