quick spring shim question
When installing shims do I remove the factory seat and place the shims under it or do I place them on top? Also do you just remove the valve guide to remove the stock seat?

You'll usually end up destroying the seal after you remove it, so plan on replacing them. Just don't replace them with the 1pc seal/seat combo GM used for a while. It will move the seal up and decreases retainer-seal clearance as well as the seal's hold on the guide.
And no, don't remove the guide to install shims.
