Running the springs you have that tight may not be feasible, in addition to the fact you broke one they already may be hurt. I would look at the PAC or PSI, they coil bind a little higher. You can get away with as much as .120 to coil bind, but the idea is to use a valve lift that matches the spring when you start running more than about 7500 RPM. That way the seat height and open height are optimum for spring, putting coil bind height where it need to be without excessive seat pressure. Mine ended up with .075 intake and .095 exhaust distance to coil bind.
