Is there a chart or anything that tells you what spring does what? Does the adjustable regulator pretty much negates these? What "recipe" would you all recommend (stock, good shape timing cover with wear plate) with the .002-.004 clearance, as in spring color? Any set adjustment to the regulator, or just get it to whatever number you see fit? I know the regular has nothing to do with idle PSI. Thanks for your time.
White should be 60 psi. There used to be instructions with the oil pump when given new springs. I think orange is 40.

We are running the TA Performance front cover with the new oil pump already bolted on from them. Engine makes 80psi cold oil pressure, but once fully warmed up, it usually drops to about 30-35 psi at idle, and 60 psi when driving. We were thinking of going to a thinner oil, as she is still on break in oil. (I believe it's 20W)
