Well i have a set of Crane 144832 dual valve springs good to .650 lift for sale that i was running with my ms3 cam and stock heads. I also have the matching Crane titanium retainers 144832 and locks to go with them. I just picked up a set of heads and have 2 sets of springs to go with so i no longer need all 3 sets. They have just shy of 500 miles on them and are basically brand new. New the springs cost $160 and retainers cost $240. I will let everything go for $250 shipped. These are awesome springs and retainers and will hold any high lift cam. I accept paypal. Check me out on ls1tech.com i have
