If you are running an aggressive lobe cam, you need a stiff spring and I would run travel limited lifters. I would get the spring specs, i dont trust anyone with head set up, i do it myself. Most of these cars dont have enough springs. Do you have the cam card? That is a lot of duration, I dont think you are going to be happy with it. Overlap might be too much to work well with the 3 bolt turbo too. That is way more duration than I have in my 8 sec car.
