Hood spring question

My question is on a 67 barracuda do you have to load the spring as in giving it a full turn somehow for it to hold the hood open? The way it is now i have to use a prop stick and dunno if the springs are just that worn or if I just assumed wrong when I initially installed them. The car didn't have them on to begin with so I have nothing to refer on what the stiffness of the hinges should be but I'm pretty sure it's not what I have lol
