TOO MUCH VALVE SPRING

oldkimmer said
Take out the inner spring or raise the installed height another .050 to 1.750. But u first need to know where your at right now. The machinest should know. Kim

How would you raise from 1.7 to 1.75 if the space under the retainer is only 1.7?

Edit: 120 psi seat, and 300psi @ 1.180 (this open height was the lift these springs were originally chosen for. My lift is substantially lower).
