well, i am about to do an oil pump in my car and while reading up on different posts, i saw where some guys are shimming them. i tried doing a search but couldnt quite find what i was looking for. how do i know if i need to shim, how much i would need to shim and where exactly do they get shimmed at? on the pressure side or relief side? i am looking at ls6 pumps. not sure if i am going ported or not. depends what i find. thanks for the info!!
