That's what PSI tech recommends regarding the coil bind distance with their springs.
Again, this was years ago.

Hi Steve: I just received information from PSI tech on my springs and they are more than .100 from coil bind, and he said if you have no issues such as break up, valve float, broken springs, valve seat wear, at higher rpm to carry on. He did say we recommend .060"-.100. He said you would be just adding extra load on the valve train.
