I would'nt use a single spring on that cam profile , they will probably break.
Mine did, almost lost the motor.
[The PAC single valve springs will use your factory seats, seals, retainers, and locks! We recommend stepping up to a dual valve spring kit if you plan to run more than .600" lift and/or a valve larger than 2.08" diameter.]
Good advice
