Light weight hood springs, how tight to wind ?

Getting ready to install my new light weight hood springs on my 68 Cuda :)
How tight do I wind them ? Do I just slide them on loosely or try to turn them a 1/2 turn or so more more lift tension ? Looks like a ***** to do that .
I got them from a guy on here awhile ago .
Fenders , splash shields , and hinges are off the car
Any tips or tricks guys ?
Thanks
Donnie
