a buddy of mine did a valve spring upgrade to his stock heads... apparently he forgot to install on of his pushords on cylinder number 1..(it was the exhaust side). He fired the motor up and it ran for about 6 to 7 seconds max.... of course a loud slapping sound was heard and thats when it was shut down and i told him to take valve cover off and noticed no pushrod.... now..with that being the exhaust side pushrod.... if he puts that pushrod back in and refires it... it should be fine, right?? if not do u think it fk'd anything up... thanks!!!
