Need to shim valves to fit 1.8" Yella Terra rockers?

I have an LS6 with stock LS6 heads. I am looking to replace my valve springs soon and would like to upgrade the roller rockers while I'm at it. Will I need to do any modifications to fit 1.8 inch rockers?

The rockers need to be set up to obtain the correct wipe pattern first. Also, not sure the LS6 valve springs will keep up with 1.8 rockers, you may need to upgrade to better springs. PAC makes some good valve springs you can upgrade to.
