Would you buy slightly used valve springs?
I'm not sure what they are comming out of. They are going in a basically stock ZZ4 with 1.6 rockers. I need new springs to accomodate the added lift. The exhaust valve will coild bind with 1.6 rockers. These springs will give me .600 lift set at the standard height of 1.8. I will get .580 lift set at the zz4 height of 1.78 inch. They are CompCams behive springsWell, what kind of motor did they come out of? And what kind of motor are they going into?
