Ass additional back ground, I have tested all my new springs using 42 mm for seat pressure for both intake and exhaust, 30.5 mm for intake full pressure, and 31.5 mm for exhaust full pressure.

The target value for the seat pressure is 44 psi +/- 5%.
The target value for the intake full pressure is 176.5 psi +/- 5%.
The target value for the exhaust full pressure is 165.3 psi +/- 5%.

The seat pressure values for the new spring range from "in Spec to 6 psi above the high range" for the spring being acceptable.

The intake full pressures for both intake and exhaust applications are within the range for the spring being acceptable.
