no no , sorry for confusion. you need both springs. Just remove the heavier spring from the distrib and replace with one from the mr gasket kit( both springs in the mr gasket kit are the same) Doing so will allow the advance to come in quicker. And like I said you will have more of a noticeable off the line quickness if you adjust the initial timing higher. I have mine at 10 degrees. But not past 32 degrees total timing on a slant six.
