yes i think you will be all right but i would not rev it up high. the best thing to do is just change the springs they are cheap and you have to put new lifters in anyways if the cam is not roller. they make kits that put air into the cyl so you can change the spring on the car with out the valve falling down and you dont have to take the heads off
