your changing all the springs, and you may look into shimming the springs also, increases seat holding pressure even with those springs, I think its .030 if I remember right, thats the shim thickness, summit sells them. I would do that if I was running above 40psi boost all the time, its the turbo drive pressure that you have to worry about. Thats what floats the valves.
