DSM Valve Spring Seat Pressure Comparisons

In case you are needing to know spring seat pressures for various DSM valve springs, I compiled this chart.
It doesn't cover EVERY spring made but most of the brands that our vendors supply for comparison.
If I need to add any others, just let me know and I can put it on the list!
