I just went out and checked my pushrods and all were straight except one it is bent just a little is the an allowable amount I am guessing if it is bent a little it will bend under pressure. I have another pushrods but it is about 1/16 inch longer than the rest. Will that affect anything or will the rocker arms just adjust to take up the extra length ? Also when adjusting the cold valve lash what are the clearances and how do you know with all the rocker arms loosened up when the piston is at top dead center?
