I like using a solid roller so I will stick with it.I have no idea how much I can regrind the cam to so thank you for your info! and help!I am looking at some roller cam,spring rates just to get an idea of what I may need like the Comp 23-703-9 .582/.588 110 that would need a spring 953-16 200# seat 496# rate and I will test my other springs I have to see if they will work to help plan.I need to have my roller lifters looked at to check their health to re-use.
ps:Here are 2 springs I have .1 is a 943 at 550# inch and the white stripe I am not sure of
