Spring pressures seated & open
I am contemplating a Cam install soon. Approx .600 lift. Some say use PATRIOT GOLD and others say use PATRIOT GOLD EXTREMES, whats the difference in spring pressures seated & open. I need some opinions from those who used them. Things like longevity etc are a concern.
