shiming an oil pump?

Re: shiming an oil pump?
How do you know what thickness shim to use to gain lets say 5 psi? Or is it just more of a guess? How much psi is to much psi?
I am working on and ls and wanted to add just a bit. The owner may one day want to go with a b16a head would this be a good idea (adding psi)?

Ok nice my b oil pump has a y off the pump one to the oil psi control valve/spring and one going to the motor. So I should not have problems will low pressure at idle. I did a lot of measuring and found what the installed height of my oil spring is and what the shim I am using. It should bump installed height 4% but I do not think I will get 4% oil psi bump probably closer to 10%. I do not think springs are linier. My old machine shop had one off the valve spring tester I may con him into measuring the tension with a washer and with out to see when the spring will open.
I am planning on using a .065 shim LOL. My goal is going from 50 to around 55-58. Dose this all seam useless? Will to much psi hurt?
