well im installing a set of CROWER 403 cams and valvesprings and retainers in my LS tomrrow. i was looking at the spring's and noticed that they have almost the same spacing between each loop of the springs at the top and the bottom. i probably confused some of u by that sentence so let me try to rephrase that.
U know that in the stock springs, the bottom of the springs are more tightly wound together than the top of the springs. this is how u determing the top and bottom of the spring (also the color on the springs helps too) but on the CROWER springs, the winding on the top and bottom look the same, so i dont know which is the top and which is the bottom. can u install the springs in any side cuz they both look the same to me.
