Hydraulic lifters as a rule have a lot of forgiveness it them. with a relatively mild application and normal usage you will be fine as long as the lifter plunger is not bottoming out in the lifter. If the lifter plunger bottoms out and is tight it will hold the valve open much the same as adjusting a solid lifter with no lash. If this is happening there is a no start or the least a very poor running condition.
