My hemi has a melling HV pump on it and both it and a new 1 I have came with the plain color high pressure spring. With 10W-30 Mobile 1 it has 55psi hot at idle but the lowest I can idle with my solid roller is 1100 rpm. By 2,000 hot it's up to 75. It is 75 cold idle. Max pressure can get to 100. It was higher than I liked so I tried a standard melling with pink spring and it did lower idle but seemed to max out around 45 psi. Too low. So my only choices is to trim plan spring to lower max pressure or shim standard spring to increase pressure.

I wouldn't have any problem with your current pressures but if you want more at idle put a HV pump on it and use your pink spring since it gives you 60psi which is plenty.
