I currently have pac 1201 valve springs and want to know if you guys think they will last with my combo. I want to be able to run 6000 rpm. My cam lifts about 0.510. The springs are at 1.72 installed height to put seat pressure at 152#. Which puts open pressure at around 430#. Will be running Johnson restricted travel hydraulic roller lifters on a comp 210/210. Is this a reliable set up? Do you recommend different springs or seat pressure? Thank you!
 
I just want to know that it can run safely up to 6k. Not saying I will try for that or reach it. I realize the turbo is more of a determining factor with trap rpm. Just want to know mainly that the pac 1201 is a strong enough spring I guess
 
With a 210/210 cam, you will not be making any more power beyond 5500. But your springs will be OK.
