How to shim the oil pump
Hi, I am doing a cam swap on my friends z06. I wanted to shim the oil pump for another 10 or so psi. I know the shim goes on the pressure relief valve, but on what side of the spring? Does it go valve, shim, spring, plug, or do I have it reversed? Also, what size shim should I use? Thanks for the info!

~0.125" = ~ 10psi.......
valve, spring, plug (with shims inside plug).....
